Too Many Birds At Ding Darling NWR

The title of this post is made in jest while it's somewhat accurate with regard to my perceptions for bird photography at J. N. Ding Darling National Wildlife Refuge of late.

The Great Egret with White Ibis above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

Of course, an early morning visit to the refuge at a low tide is the ideal time to be here for wildlife observation.

At that time, the rising sun will be for the most part behind you as you make your way along Wildlife Drive.

The Roseate Spoonbill above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

To clarify earlier comments made related to the importance of the tidal conditions, it is best to arrive at Ding Darling four to five hours after a low tide at Matanzas Pass timing a visit as close to sunrise as possible.

The time of an ideal low tide will vary depending on the time of year of your visit.

The Ring-billed Gull above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

Biting sand gnats can be a nuisance at the Refuge as I've observed in virtually all of my visits, so you may want to have an insect repellent with DEET available.

Please note that if viewing the exif data for any of the photographs taken this week that I failed to change the time ahead an hour in my camera.

The White Pelican above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

I've observed the tide to change this many hours after the low at Water Control Structure 2 with predictability.

My last three visits to the Refuge have been particularly overwhelming in the wildlife seen.

The Roseate Spoonbill above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

This smacks in the face of commentary I've been told or read that there has been a reduction in wildlife observations made in recent years across the state of Florida.

I've given some thought to this perception and what the explanation for it may be.

The White Pelican above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

I have been diligently observing wildlife in southwest Florida for about four years with 12 favorite venues that I visit as regularly as possible.

These southwest Florida venues include Ding Darling, Bunche Beach, Estero Lagoon, Lovers Key, Harns Marsh, Lakes Park, Corkscrew Swamp, Six Mile Cypress, Venice Rookery, Eagle Lakes, Tigertail, and Babcock Webb in no particular order.

The Double-crested Cormorant above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

So what might be the cause for such a negative perception of a wildlife decline?

I can think of a few things that may have different degrees of relevance.

The Great Egret above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

Foremost is perhaps the unprecedented back to back hurricane seasons of 2004 and 2005 when hurricanes Charley, Frances, Ivan, and Jeanne in '04 and Dennis, Katrina, Rita, and Wilma in '05 undoubtedly devastated countless nesting colonies.

Hurricane Charley is particularly noted as having changed the ecology and topography of Ding Darling NWR.

The Double-crested Cormorant above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

Hurricane activity in Florida has fortunately been subdued in more recent years giving wildlife the opportunity to recover with more favorable conditions.

Abnormally cold weather the last two winters has possibly impacted birds favorably in Florida with the '09-'10 fish kill when wading birds gorged themselves earlier than they typically do when water levels are at there lowest before the start of the rainy season.

The Great Egret above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

A comment overheard by a volunteer at Ding Darling noted however that rainfall, whether plentiful or not, has not been a cause of the failure of Wood Stork nesting colonies at Corkscrew Swamp Sanctuary the last couple of years to the extent that cold weather has been.

Wood Stork have been seen in the Fort Myers area with frequency this winter (though not this past week), particularly at Ding Darling NWR and Harns Marsh Preserve.

The Pied-billed Grebe above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

In addition to the above speculated uncontrollable forces, I've made observations that have negative impacts from moment to moment.

Most recently was an observation of a few young kids at Estero Lagoon that were running into a flock of resting birds near the surf.

The playful activity above was photographed at Estero Lagoon in February 2011.

This event reminded me of kids doing the same on the flats at Lovers Key State Park at New Pass with much greater numbers of birds impacted a few years ago.

The lack of parental supervision is disappointingly seen with positive efforts made at Ding Darling noted recently as a bus load of kids passing by were heard educated about the wildlife they could see.

The Pied-billed Grebe above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

The education about wildlife has been made in the form of questions like, "What do you see?"

On occasion I've also observed pets that are allowed to run unrestrained by their owners with the dogs as expected attempting to play with wildlife which reacts as you might expect.

The White Ibis above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

I'm not sure the impact of exotic pet release or hunting, but these factors may have notable impact for observations of wildlife as well.

Florida has allowed the hunting of snakes in the Everglades this past year.

The Belted Kingfisher above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

I've encountered an abundance of wildlife during my visits to the venues mentioned in this post with very rare exception.

Ding Darling NWR was my sole focus this week devoting much time along Wildlife Drive at my favored observation point at WCS2 with numerous observations made that were no less than extraordinary.

The Little Blue Heron juvenile above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

As was normal in the moon's cycle, the favored low tides had been getting higher and later in the morning each day.

I believe this was the cause of fewer birds seen overall on each successive visit to the refuge while the most recent visit I found to be the most memorable.

The Pied-billed Grebe above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

A Swallow-tailed Kite was seen for the first time this season as it gracefully circled above.

Toward the west near mid-morning I thought I observed smoke rising into the sky, but it was thousands of Tree Swallows upon closer inspection.

The Swallow-tailed Kite above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

There were many opportunities to observe feeding behavior, overflights of birds, and the mere daily routine of the interesting avian creatures.

I was able to photograph for the first time the double crest of a cormorant which is not an easy thing to do even considering how abundant this species is in the area.

The Tree Swallow with egret above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

An adult Snowy Egret was not tolerant of a juvenile that was within its territory.

A distinctive waterfowl observed flying with a pair of Mottled Duck would be identified as the rarely seen Northern Shoveler at the Refuge.

The Northern Shoveler above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

And perhaps the most exhilarating experience was an overflight of about a hundred Willet that strafed me at less than ten feet from behind.

The allure of Indigo Trail has been incredibly enticing, though yet to be explored.

The Willet above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

Too many birds at the refuge has been my concern for a photograph of the wildlife without a distraction in an image taken of a particular subject ideally engaging in behavioral action.

I'm not a fan of manipulating photographs beyond traditional means though desperately need to learn how to add canvas to an image which I hope to do in the near future.

For returning visitors to my blog, I hope you find the new look appealing.

I'm grateful to Tim Rucci for his help with my Pbase style sheet while attempting to emulate it in this blog.

The Pied-billed Grebe above was photographed at J. N. Ding Darling National Wildlife Refuge in March 2011.

I cannot emphasize enough the importance of timing visits to venues nearby the Gulf of Mexico for the most part at a low or near low tide.

If you fail to do this, you may end up being disappointed.

Mockingbird Nocturnal Audio



As I've mentioned before, the documentation of bird behavior is becoming a greater interest of mine.

The Reddish Egret above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

Normally I would be presenting images here taken this past week, but due to much time spent doing research and recording birdsong as opposed to photographing wildlife, the images are for the most part from my previous week's trip to Ding Darling NWR.

In the last six weeks or so, there has been interesting nighttime activity of birds that have been making brief stops near my residence for a few days at a time or less.

The Great Egret above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

This week involved a bird not seen until the third day when I put the beam of a flashlight into the tree to determine the species making the racket.

After determining the bird to be Northern Mockingbird, I had thoughts of the video of the Sir Attenborough study of the Superb Lyrebird in Southern Australia.

The Snowy Egret above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

The Lyrebird is noted to remarkably imitate upwards of 20 other bird species, a car alarm, a camera's shutter mechanism, and a chainsaw cutting the forest within its surroundings.

While I'm very unlikely ever to see or hear the Lyrebird firsthand, another bird species that is perhaps equally as interesting is the appropriately named Northern Mockingbird.

The Tricolored Heron above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

The mockingbird and starling are species of bird that are adept imitators.

I often see the Northern Mockingbird in my efforts to observe wildlife but rarely hear its call.

The Red-breasted Merganser above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

The Northern Mockingbird is the state bird of Florida and four other states.

The male mockingbird is commonly known to be heard at night (unlike most other bird species I'm aware of) with its song certainly an effort to attract a mate.

The White Pelican above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

The recording of bird song with high tech recording equipment that I had anticipated engaging in during retirement is unexpectedly underway with nothing more than my cell phone and computer.

Recording attempts were made over several nights ranging from minutes to over an hour where through practice I was able to figure out what I was doing.

The Pied-billed Grebe above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

One 30 minute attempt was met with failure as I accidentally turned off the recorder when I placed the phone strategically in the tree's branches.

With a total of about two hours of mockingbird recording under my belt within a half dozen files, I began my investigation of a way to offer the best and longest recording to you here.

The Red-breasted Merganser above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

The drone of distant automobile traffic was regretfully unavoidable even at two o'clock in the morning.

I am impressed with how Birdjam presents its audio capability and asked them if I could emulate their service.

The Ring-billed Gull above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

I received a prompt reply advised to utilize Youtube as an entry level approach.

That wasn't considered the best help, so I began research on other options of having an audio file of the mockingbird's song accessible here.

The Snowy Egret juvenile above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

A lot of time was spent with a solution determined if you ever have an interest in uploading an audio file created by a cell phone.

The phone's AMR file conversion to a computer friendly one I was unsure of.

The Double-crested Cormorant above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

Conversion to an MP3 file verses a WAV file was decided upon due to the former reportedly usable with more computer programs.

It may have been a poor choice as the 76 minute AMR audio file at just over 7MB of memory converted to 105MB which seems like a comparatively awful waste of space.

The Red-breasted Merganser above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

My conversion of the AMR file to MP3 was made by a program provided by Miksoft which I highly recommend for its speed and simplicity.

I will return to Miksoft to make a donation for their resourceful product.

The Ring-billed Gull above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

Then was the decision that had to be made of the host for the file where I investigated four options other than Youtube.

I first looked into Fileden which I frequently see affiliated with many of the musical songs that are incorporated into the Playlist gadget seen here.

The Reddish Egret above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

This is where I wasted most of my time as I encountered a "fatal" error when attempting to become a member.

I really like the slick appeal and "simplicity" of Uploadrobots, but hit a snag there when the MP3 file size of the Northern Mockingbird recording couldn't be uploaded with the constraints of their free service.

The White Pelican above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

Filedropper was also investigated where I reached the point where a file became available to "download."

Since I know you don't want to do that, I then had the best impression with 4shared.

The Reddish Egret with Double-crested Cormorant above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

The upload of the relatively large audio file transferred at 4shared extremely quickly in comparison to Fileden.

Well, let's get back to the mockingbird.

The Osprey above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

The bird was very entertaining to study and hopefully worth your interest in listening to.

I've found the bird that had chosen to perch in a tree closest to me to be stunningly varied in its song.

The mixed shorebirds above were photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

This bird was the most adept with two of his competitors heard at greater distances clearly not having anywhere near the diversity of song.

The Northern Mockingbird male is thought to have between 50 and 200 songs in its repertoire.

The Red-breasted Merganser above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

With my longest recording at over an hour, I haven't had the time to determine if the bird repeats its song within it.

I wish I were more more knowledgeable of song and calls of different species as I can only recognize a handful of them in the recording and hope you can help identify them all.

The Red-breasted Merganser above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

The image of the band of Bald Eagle 862 is presented below as promised with another angle of it offering additional detail.

The juvenile eagle should be near ready to take flight from its nest with no competition for food from a sibling as observed this year.

The Bald Eagle above was photographed at Lovers Key State Park at Big Carlos Pass in January 2011.

Please consider enjoying the song of the Northern Mockingbird by pressing play at far left of the gadget below . . .

SWFL Early 2011 Birding Bonanza

While typically attempting to highlight a particular focus of interest here in Southwest Florida, I'm this week able to report on a handful of venues of great interest to me and hopefully you as well.

The Savannah Sparrow above was photographed at Devils Garden in February 2011.

I missed seeing Tom Obrock at STA5 last week as I would especially find it an enviable opportunity to accompany such an accomplished birder as himself to learn from.

Frank Constantin made his rounds of the local area while I regret not being able to meet up with him either.

The Snail Kite above was photographed at Devils Garden in February 2011.

Devils Garden Bird Park is a venue I was compelled to visit while I had the chance after hearing enthusiastic comments about it.

Devils Garden was officially opened to public wildlife tours in late 2010.

The Red-shouldered Hawk above was photographed at Devils Garden in February 2011.

The full day (9-4) tour was made with Jose Santiago as guide while accompanied by a fun couple from Minnesota.

I had thought Snail Kite were prolific at Harns Marsh Preserve, and then STA5, but Devil's Garden has the best opportunity to view this species of bird at close range I've yet to see.

The Limpkin above was photographed at Devils Garden in February 2011.

Jose told about the farming endeavors made on a visibly small portion of the 7000 acres that encompass Devils Garden.

He noted the hunting characteristics of hawks preying on doves that are flushed from the stands of sugar cane that serve as wind breaks for the vegetable plantings.

The Eastern Meadowlark above was photographed at Devils Garden in February 2011.

The tour additionally traversed the working ranch's wetlands, tree hammocks, and prairie wildlife habitats.

A stunning Northern Harrier was observed though stayed tantalizingly just out of photographic range.

The Red-shouldered Hawk in its nest above was photographed at Devils Garden in February 2011.

A never before seen nest of Red-shouldered Hawk was a highlight of the tour.

In addition, a nice sighting of a pair of American Bittern at very close range was made at Devils Garden.

The alligator above was photographed at Devils Garden in February 2011.

Sandhill Crane, White Pelican, Eastern Meadowlark, Savannah Sparrow, Osprey, Tricolored Heron, Crested Caracara and additionally seen wading and shore birds were welcome as well.

A future visit to Devils Garden will perhaps involve my investigation of one of the venue's covered viewing platforms.

The American Bittern above was photographed at Devils Garden in February 2011.

Additional visits to the venue will be required before I'm confident in "designing my own tour" of Devils Garden to take full advantage of its offerings.

Jose also commented that we have had little rain these past weeks.

The Red-shouldered Hawk above was photographed at Devils Garden in February 2011.

This certainly doesn't favor Devils Garden and its birds when compared to the conditions at STA 5 where the water is intentionally pumped into its cells.

Six Mile Cypress Slough Preserve was overdue for a visit and thus spent a morning making my way along the boardwalk at this venue that I strongly encourage you to visit.

The Pileated Woodpecker above was photographed at Six Mile Cypress Slough Preserve in February 2011.

The Carolina Wren is a species expected to be seen here, but is too often missed.

The Pileated Woodpecker was also a species of interest at Six Mile Cypress as it foraged near Otter Pond with the water's namesake yet to be seen.

The Carolina Wren above was photographed at Six Mile Cypress Slough Preserve in February 2011.

A follow-up trip to J.N. Ding Darling NWR this week was timed to take advantage of a low tide which I've found to offer best conditions for wildlife viewing at this jewel on Sanibel Island.

My expectations were exceeded with a greater abundance of wading and shore birds than ever seen before along Wildlife Drive.

The White Pelican above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

At first light, it was particularly entertaining to observe the feeding behavior of snowy, great, and Reddish Egrets, not to mention the White Pelicans at very close range.

I found myself particularly entranced as well by no less than a dozen Red-breasted Mergansers that I have not had the opportunity to study at such close range and for such an extended period of time before.

The Tricolored Heron above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

The White Pelicans were much closer to the drive than seen before with their trek northward soon to be underway.

It was interesting to observe Tricolored Heron to have dominance over Little Blue Heron with control over a pair of logs fallen in the water.

The Snowy Egret above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

A very unusual observation of a Double-crested Cormorant was made where it is undetermined whether the bird was engaged in nesting, playful, or feeding behavior with a stick.

I overheard a refuge volunteer note that low tide occurred at 6:00am while low tide took place at 1:00am at nearby Matanzas Pass.

The Double-crested Cormorant above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

A 1:00-2:00am low tide at Matanzas Pass is thus the time we need to be noting ideally with the refuge opening at 7:00am while remembering that Ding Darling is closed to the public on Fridays.

Great numbers of shorebirds flew in to the primary area observed while many dozens of visitors had moved on.

The Osprey above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

Closing out my wildlife observations for the week, I had the chance to meet up with Hemant Kishan visiting the area for observation of Bald Eagle 862 and its nest at Big Carlos Pass.

The adult eagles were regrettably not cooperative in staying within view of the nest through much of the early morning while the juvenile laid low.

The Western Sandpiper above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

After investigating New Pass nearly two miles south where Double-crested Cormorant with Brown Pelicans and an Osprey hunting for a meal were primarily observed, Hemant and I headed to the southern end of Estero Lagoon at his recommendation.

The target species was Snowy Plover with anticipation of seeing more from my perspective as I had never walked on this particular ground before.

The Red-breasted Merganser above was photographed at J. N. Ding Darling National Wildlife Refuge in February 2011.

A small flock of Royal Tern was initially seen (with one of the species in the group sporting near prime breeding plumage) in the company of quite a few Forster's Tern with a solitary Common Tern and a couple of Laughing Gull.

Numerous resting Western Sandpiper were in this group of resting birds as well.

Hemant Kishan above was photographed at Estero Lagoon in February 2011.

The walk was led by Hemant from Big Carlos Pass whom was very familiar with his surroundings and the wildlife that could be seen here while many personal walks from the Holiday Inn south never reached this point.

When Hemant returned after walking ahead of me, he noted that he had seen Red-breasted Merganser and American Oystercatcher which I would attempt to photograph as he left the beach to meet up with his family.

The American Oystercatcher above was photographed at Estero Lagoon in February 2011.

Hemant also told me that he made a rare sighting of and photographed a Great Black-backed Gull near the Big Carlos Pass bridge adjacent to the Gulf of Mexico.

I finally heard from the USGS bird banding laboratory late this week regarding my inquiry of eagle 862 with my surprise that they are requesting additional information from me.

The Great Blue Heron above was photographed at Estero Lagoon in February 2011.

I'll be seeking a more timely and efficient resource to submit information about and learn of banded birds and their history.

All of the wildlife venues mentioned above are deserving of as many repeat visits as possible.

The Snowy Plover above was photographed at Estero Lagoon in February 2011.

I will include an image of eagle 862's band engraving in next week's blog entry.
