Thomas Creek – Specialty Breeding Species

This morning Marie and I decided to kayak up Thomas Creek from the boat launch area at Thomas Creek Preserve in search of some of the localized breeding species like Hooded Warbler, Prothonotary Warbler, Acadian Flycatcher, and Black-bellied Whistling-Ducks. We got to the ramp just before 8AM on a pleasantly cool morning and headed out. If you head right downstream, it eventually takes you into the saltmarsh and becomes fairly tidal; heading left takes you further upstream and into the hardwood swamp; that’s where we headed.  (eBird list here).

Kayaking Thomas Creek

This area is very beautiful, serene, and fairly unlittered (all things considered). We didn’t see much in terms of wildlife (no snakes, alligators, or turtles), but did have a few Yellow-crowned Night-Herons along the way. I was worried about bringing my good camera, so these shots are with my lesser Nikon and thus the images are not something I’m very proud of.

About a mile upstream, we started hearing Prothonotary Warblers singing to add to the incessant singing of Hooded Warblers, which had been serenading us the entire morning. Unfortunately, the numbers of Prothonotaries seems to be “down” here compared to previous years, but perhaps we just went a little early in the season.

A little further along we started to hear Acadian Flycatchers, and I managed a really terrible picture of one and then recorded one calling. As bad as these recordings are, they’re significant because they’re the earliest Acadians ever recorded in Duval County!

That picture is bad, but notice those long primary projections! Who needs to see the rest of the bird? 🙂 Guess it’s a good thing I can review my own eBird reports, huh? (Yes, I was recently asked about that as if I just approved anything I wanted to invent; the important thing is that I actually document almost everything to make it verifiable).

We also saw a scattering of gorgeous “Spider Lillies” along the way, which would’ve made the outing great regardless of anything else.

So, we managed three of the target species, and missed on two stretch goals (Black-bellied Whistling-Ducks and Swainson’s Warblers).

Glauczilla and others at Huguenot

I started this morning at Fort George Island hoping for a few migrants but so far migration has been incredibly slow for passerines. After an hour or so, I decided to head over to Huguenot and practice my photography some more. I spent the morning shooting in shutter priority mode and manually set the ISO and shutter speed; I still don’t quite know what I’m doing but I am realizing some good results so far.

As I pulled onto family beach area the two Whimbrels were really too far away to photograph very well, so I settled on this “Western” Willet.

“Western” Willet

I still think most people don’t spend enough time appreciating the differences in the Willet sub-species; they really are almost two separate species and distinctly different looking birds. We have “westerns” throughout winter here and most depart in late spring, leaving the “easterns” to breed locally. We rarely see a “western” coming into alternate plumage like the bird depicted above. I’ll try to get a similar shot soon of an “eastern” to compare.

After birding the lagoon I headed around the north point and was hoping to practice more on some gulls, but did not expect to find this Glaucous Gull sitting there! (I like to refer to them as “Glauczilla” due to their size).

Glaucous Gull (juvenile)

Glaucous Gulls are pretty rare in Florida but they do occur at Huguenot at least annually (reports are from almost every year the last 20-30 years), but most records are from winter. Spring reports of the species include 4 April 1974, 24 May 1975, 8 April 1978, 5 May 1979, 23 April 2009, and 4 April 2014.

I then found my first Sandwich Terns of the year and am fairly happy with this image, which I shot from my truck. I am not happy with the band on one of their legs, but at least it’s a single small band and not the multiples we see on other species.

As I was leaving I watched this Great Blue Heron feeding along the lagoon.

Banner Day in Dayson Basin!

April 7, 2017

This morning a group of 15 birders visited the U.S. Marine Corps Support Facility – Blount Island, Dayson Basin, where we drove the length of the 2.5 mile elevated berm around the property. We made five stops for stationary observations. We were greeted by chilly weather conditions with temperatures in the low 60’s (F) plus wind chill; by the end of the excursion the winds had settled down and the bright sun and clear skies had made things a little more comfortable. The area had experienced two days of significant rainfall earlier in the week, but it is unknown to these observers if that had any effect on water levels or conditions inside the basin.

Over a four-hour period the group observed 71 species of birds (a small handful were only observed just outside the gated portion of the property but nevertheless directly adjacent). Species observed that are known to breed locally and appear to be in suitable habitat on the property include Canada Goose, Black Vulture, Turkey Vulture, Osprey, Clapper Rail, Black-necked Stilt, Wilson’s Plover, Killdeer, “Eastern” Willet, Red-bellied Woodpecker, Downy Woodpecker, Blue Jay, Fish Crow, Carolina Chickadee, Tufted Titmouse, Marsh Wren, Carolina Wren, Northern Mockingbird, Northern Parula, Eastern Towhee, Northern Cardinal, Red-winged Blackbird, and House Finch. The group did confirm occupied nests for Canada Goose and Osprey on this visit. We also observed Blue-winged Teal and Ruddy Duck in the basin, two species that have been known to breed in Duval County in very few years historically.

We observed 5 species of waterfowl, including significant numbers of Northern Shoveler (250). A group of 108 American White Pelicans loafing in the middle of the basin is notable for northeast Florida in any season.

American White Pelicans

Raptors included 3 Osprey, two of which were actively visiting and then defending a nest atop the cell tower. We did not detect any young in the nest. Bald Eagles numbered 6, including 2 adults, 1 third year bird, and 3 immatures.

We recorded 16 species of shorebirds, including 40 Black-necked Stilts, 350 American Avocets, 650 Semipalmated Plovers, and 1,250 Least Sandpipers.

Black-necked Stilts breed in limited numbers in Duval County, but locations such as Big Talbot Island’s Spoonbill Pond are subject to nest predation by raccoons and other predators. The group is encouraged that Dayson Basin appears to provide natural deterrents to such predation (extensive mud, etc.) and are optimistic that the Stilts can breed here rather successfully.

The number of American Avocets using the Basin is simply incredible; the 350 observed this morning likely constitutes the most ever recorded in NE Florida. American Avocets are a medium-distance continental migrant and are known to be less common in spring than in fall migration. Avocet observations in Duval County usually consist of small groups of 5-40 birds in nearby White Shell Bay during low tide in winter. To see numbers of them and in magnificent alternate (breeding) plumage was spectacular.

We observed 4 Wilson’s Plover in the basin; these plovers are known to breed locally at Huguenot Memorial Park and Talbot Islands State Parks. It is possible they breed in the basin, as conditions there seem favorable.

Semipalmated Plovers breed in the sub-Arctic region and we observed 650 or more of them in the basin this morning actively feeding. Stilt Sandpipers winter in central South America and breed in the low arctic tundra; they are very uncommon in NE FL where small groups are usually found at Big Talbot Island State Park’s Spoonbill Pond in migration. The eighteen-plus recorded in the Basin is a high number for the area and reinforces the importance of this location for medium and long distance migrants to recharge.

Least Sandpipers are a common migrant shorebird in NE FL but the numbers today (1,250+) represent an extremely high concentration for the species. The 350 Long-billed Dowitchers noted is also significant; the only other semi-reliable known habitat for them in Duval County is Spoonbill Pond.

The concentration of shorebirds undoubtedly attracts attention, and we observed two falcon species (Merlin and Peregrine) hunting for prey just after dawn. As previously noted, up to 6 Bald Eagles were also patrolling the area. Note: to see 6 Bald Eagles anywhere in NE FL at the same time is another remarkable observation.

The perimeter of the Basin is also well maintained for attracting migrant and resident “land birds”. We observed 20 species of passerine around the 2.5-mile drive.

It is always a noteworthy achievement to record over 70 species in any location in a single visit, and that has only been accomplished in NE FL seven times previous at 4 other locations in Duval County. Dayson Basin is indeed an “important bird area” by any measure.
