Lesser Black-backed Gulls at Cape Henlopen SP

Taj Schottland and I spent Saturday morning at Cape Henlopen Sate Park scouring the veg for migrants. We found a Common Yellowthroat, Ruby-crowned Kinglet, and two Red-eyed Vireos. Pretty lame, right? It got better as soon as we walked out to the beach near the hawk watch. We found a decent-sized flock of gulls resting on the beach containing Laughing, Ring-billed, Herring, and Great and Lesser Black-backed Gulls. There were five Lesser Black-backed Gulls mixed in with the flock. We later had two flyovers.

Lesser Black-backed Gulls are relatively common along the Delaware coast in fall and winter, but can be found year round.

I cannot remember the ages of all five gulls, but I have photos of at least three different birds. Two adults and one immature bird. I don’t have much experience with ageing, but I think the immature bird is a second or third winter bird. Suggestions or corrections are greatly appreciated.

Again, let me know in the comments what you think about the ageing of these gulls. Thanks!

Until next time, bird hard my friends.
