Having missed the Everglade Snail Kite at Harns Marsh Preserve last week, I was compelled to make a follow up trip on 26 July to attempt to observe the species.
I was much more observant to find Apple Snail eggs as well. The clutch of eggs above I questimate to contain 500, well within the range of 200-600 for this invasive species of snail.
There were other Apple Snail egg clutches observed on vegetation within the marsh.

Ten Limpkin were observed before the first turn north of the parking area. As Limpkin in Florida rely almost exclusively on Apple Snails for their sustenance (as do Snail Kites), it would seem that Harns Marsh has a healthy supply of the food source.

Yet, it was again a disappointment not to see a Snail Kite. Their numbers have never been huge at Harns Marsh that I’m aware of, but I have personally seen upwards of five distinct Kites in one visit at this location. eBird checklists from Harns Marsh Preserve in recent months show Snail Kites have been present.

Everglade Snail Kites, as of this writing, appear to be making a recovery in their numbers after a staggering 80% reduction in their numbers in the ten years preceding 2009. The Audubon Florida Everglade Snail Kite Nesting Season Summary 2012 is an interesting read.

There were a total of 30 bird species seen or heard with assurance with it possible for a few more to be added if I recognized the distant call or song. A much greater effort was made to document species not photographed well, or at all, at Harns Marsh last week.

Least Bittern were very active in flight calling periodically from the get go this week. The very colorful Purple Gallinule made its appearance shortly thereafter, while Gray-headed Swamphen weren’t seen until much later after sunrise.

A juvenile Purple Gallinule was observed feeding on the same Bent Alligator-Flag (Thalia geniculata) flowers as possibly one of its parents. According to eBird historical Bar Chart data, Purple Gallinule will disappear from Harns very soon from the time of this writing for six weeks. It will be interesting to see if the Gray-headed Swamphen will follow suit with no eBird data for the invasive species at Harns Marsh in preceding years.

Even absent the Snail Kite, Harns Marsh Preserve in Lehigh Acres always offers a rewarding wildlife experience. Dragonflies were very abundant during this week’s visit though very infrequently perched in my observations. The Northern Flicker was a nice bonus.

If you have not made the effort to explore the eBird website, you are strongly encouraged to do so. The hours will pass very quickly. And be sure to make a special effort to visit Harns Marsh Preserve.
