Waders Far and Wide

Happy Autumn everyone!

Autumn is my favorite season. I’m usually the first person to wish people a happy autumn. On the 22nd I actually forgot it was autumn until about 9 pm…probably because it was 90 degrees outside! We’ve had unseasonably warm weather the past week and a half, but of course that didn’t stop us from going birding. On Sunday Dave and I took a trip to Edwin B. Forsythe NWR for our first fall birding trip.

September is always a busy time at the refuge with a mix of fall migrants and summer stragglers. It’s also peak time for waders, who could be seen all over the wildlife drive. Wading Birds are not the same as Shorebirds. Shorebirds consist mainly of plovers, sandpipers, avocets, and oystercatchers. Wading Birds refer to herons, egrets, ibies, bitterns, spoonbills, and storks. Wading birds can be found at the shore, but they are actually listed in between Pelicans/Frigatebirds/Boobies and Hawks/Falcons in field guides, meaning they are more closely related to those families than shorebirds.

We saw 6 species of wading birds on this trip: Great Blue Herons, Great Egrets, Black-crowned Night-herons, Snowy Egrets and Glossy Ibis. There were 3 Black-crowned Night-herons hanging out on an island of shrubs. We actually found them in the same place I saw my very first Night-heron on my very first birding trip with Maria (my best friend/birding buddy), so that was special.

The 6th species of wading bird was a bit of a surprise and the most interesting species for me on this trip. Dave and I were standing atop the Gull Pond Observation Tower when a medium-sized white wader landed in the water. At first we thought it was a Snowy because of its size, but then changed our minds and thought Great Egret. But the size seemed too small, and the legs weren’t quite the right color. A second bird of this species showed up.

They were also kind of, well, weird. Their movements while foraging were different compared to a Great Egret. They moved slowly, but would stretch out their necks and rock them from side to side. I feel like all the Great Egrets I’ve watched forage extremely carefully, while Snowy Egrets move quickly and erratically (sometimes I wonder if Great Egrets find it annoying to hunt next to a crazy-moving Snowy Egret lol). 

Then we noticed the bill and it all clicked. It was darker compared to the Great Egret’s bill and too light to be a Snowy.

Immature Little Blue Herons! Immature Little Blue Herons are in fact white, not blue like the adults. Why are they white? Ornithologists believe that blending in with the other egrets puts Little Blues at an advantage. Not only do they catch more fishing with the other species, but they get extra protection by blending into a mixed-flock. They are also better tolerated by Snowy Egrets, who can be aggressive towards Little Blues.  We’ve seen Little Blue Herons before (our first at Cloverdale Farm and second at Bombay Hook NWR), but these were our first juveniles. These Little Blues were fun to watch.

Other highlights of our trip included a large flock of Greater Yellowlegs, Forster’s Terns in non-breeding plumage, Double-crested Cormorants, tons of gulls, a single Osprey, a Ruby-throated Hummingbird, Wood Ducks, and a Belted Kingfisher (our first for our Forsythe list) to name just a few from our 39 species total.

I’m glad autumn is finally here, but I can’t wait for the weather to finally cool down! I’ll miss the wonderful summer visitors, but am also looking forward to the winter birds. I’m happy we had the opportunity to enjoy all the waders before they migrate.

Shorebird Central

On Sunday we took a trip down to Edwin B. Forsythe NWR. Despite the flies, Forsythe is a wonderful summer birding location. I heard that there were White Ibis around, so we decided to see if we could find this rarity.

We left pretty early in the morning and it was quiet when we arrived. We spent a little time walk around the visitor center and towards Lily Pond. At the pond we found at least 5 Wood Ducks as well as some Gray Catbirds and Red-winged Blackbirds. At the visitor center we found a Chipping Sparrow being followed by a large (compared to the sparrow) juvenile Brown-headed Cowbird. Unfortunately that Chipping Sparrow was cursed with a brood parasite. Brown-headed Cowbirds always lay their eggs in other bird’s nests, although the parasitic egg isn’t always successful (check out my post on brood parasites here).

 

Next we went to the first observation platform. It was swarming with a large flock of Barn Swallows. In the distance we were able to see a few Osprey on their nest, while also spotting Laughing Gulls, Seaside Sparrows, and Marsh Wrens. There even was a little snail crossing the platform, so he was fun to see.  At Gull Pond Tower, we saw even more Wood Ducks, a Cooper’s Hawk, a Great Blue Heron, Eastern Kingbirds, and many more Barn Swallows. The surprise bird over at the Gull Pond for me was a juvenile Black-crowned Night-heron. It was our first juvenile BC-NH since our 8/23/16 Forsythe trip.

It was Shorebird and Wading Bird Central once we hit the wildlife drive. Great Egrets, Snowy Egrets, Great Blue Herons, Semipalmated Sandpipers, Greater Yellowlegs, Dunlins, and Semipalmated Plovers were everywhere you looked. There were a few surprises scattered around too. There was a lone American Avocet among the smaller plovers and sandpipers. It was the first time we’ve seen one at Forsythe (our firsts were at Bombay Hook NWR). We also ended up finding the White Ibis! There were 2: both juveniles. They had brown backs, white rumps, and orange bill/legs. They were foraging in a group of Snowy and Great Egrets. (Sorry the White Ibis picture isn’t that great, they were really far so it was basically so we can prove the rarity on ebird)

There were plenty of Seabirds around too. These included Forster’s/Common Terns (many of them juveniles), Laughing/Herring/Great Black-backed Gulls, Black Skimmers, and Gull-billed Terns.

As far as Raptors, there were at least 20 Ospreys throughout the drive. At one point we watched at least 3 of them chase one that was holding a fish. The poor guy being chased eventually lost his fish back to the water. There were also some Ospreys chasing after an adult Bald Eagle.

We actually found a second rarity: a lone Snow Goose. This poor little guy looked like his wing was messed up, which would explain why he was still here. He waddled along the trail and disappeared into the grass.

The second half to the wildlife drive brought some more interesting surprises. There were even more wading/shorebirds/seabirds already mentioned, but on this half added Short-billed Dowitchers, Double-crested Cormorants, a single Whimbrel, Glossy Ibis, and one Ruddy Turnstone. When we were watching the Whimbrel, a small bird swam across the water in the distance. It was hard to make out, but we could see it’s downturned bill and rump sticking out. It quickly disappeared into the reeds, but we were able to figure out that it was a Clapper rail, another life bird for us.

August at Forsythe NWR is beautiful. There marshes and pools were dotted with flowers, while butterflies and bees flew to the different plants. The variety of birds at this time of the year is fantastic. We ended our day with a total of 55 species (2 rarities: White Ibis/Snow Goose and 2 life bird: Clapper Rail/White Ibis).

Stay tuned: Dave and I have been birding yesterday and today in some surprise birding locations we didn’t expect to go to. I’ll have some posts about that in the upcoming days. 🙂
