Ah, fall migration! One of the most exciting times of the birding year. As I stated in the recent Barnegat Lighthouse trip post, winter migrants have started to arrive and summer visitors are getting ready to go down South. This means that we get another chance to see warblers passing through the area, now in their fall plumage.
Saturday we took a trip to Palmyra Cove Nature Park. It started out normal enough: Wild Turkeys, a Great Blue Heron, a Great Egret, Mallards. Recently we’ve been taking the trail to the Dredge Retention Basin then the Red-wing Blackbird Trail to the Cove. This time Dave said he wanted to take the Saw-whet Trail. The Saw-whet Trail is only 1/4 of a mile, but it ended up being the busiest 1/4 mile of the day. Busy with what?
Warblers. A whirlwind of Warblers.
We were surrounded by warblers in all directions. They were flitting around the trees looking for food and chasing each other. There were other birds too, such as Carolina Chickadees, Red-eyed Vireos, Eastern Wood-Pewees, Cedar Waxwings, Great Crested Flycatchers and American Robins. But they were mostly warblers.

There are 56 species of warblers found in North America. Warblers are a diverse groups of small birds that can be found in all different colors. Sometimes male and females of a particular species will look the same and sometimes they are sexually dimorphic (males and females look different from one another). There are also some warbler species that have a “Bright” and “Drab” plumage variations. But that’s just the start. There’s spring vs. fall plumage, 1st year male/female vs. adult male/female and so on.
So the world of warblers is wonderful but it’s also…confusing. And while I was happily surrounded by warblers of many kinds, the big question became: who are they?
We did recognize a few of them; namely Black-and-white and a male American Redstart. But everyone else was a mystery. One was yellow with a black eye patch. A few had distinctive yellow and black tails. Others were gray with wingbars and yellow bellies. I had no clue who they were, but I was excited to spend time watching them.
Figuring out who they were wasn’t easy. Thankful, Dave bought me The Warbler Guide last year. If you want to learn about warblers, this book is essential for your library (you can read my review at the link above). Dave and I (as well as my friend Maria) figured out that our new warblers included: many female/1st year male American Redstarts, a Blue-winged Warbler, “Drab” Chestnut-sided Warblers, “Drab” Magnolia Warblers, and Mourning Warblers. The “drab” warblers would have been more difficult to figure out if it wasn’t for The Warbler Guide because not all fields guides are as detailed with plumage variations.
Dave was able to take a decent amount of picture so that we can try to identify the new warblers when we got home. The problem with warblers is that they are small, usually far away, and moving non-stop. Basically, they are challenging to photograph. So the pictures below aren’t the best we’ve ever taken, but I think he did a nice job considering (we don’t consider ourselves photographers, just birders who happen to take pictures of who we see).

So by the end of the day we added 4 new birds to our life list: Chestnut-sided Warbler, Blue-winged Warbler, Mourning Warbler, and a Veery (we’ve seen the male versions of our other “new” warblers, so they weren’t new to our life list). I didn’t realize we saw a Veery until a few days later. I was entering my list onto ebird thinking we saw a Hermit Thrush, but that bird wasn’t on the list under thrushes. Veery was there so I decided to see what it looked like and aha! There it was! It looked just like the picture we had.
I’m so happy fall migration is here. Have you seen fall warblers migrating through your area? Who are you seeing? Tell me about your fall warblers in the comments.
