Sparrow Migration at Sandy Hook

On Friday, someone reported a Le Conte's Sparrow at Sandy Hook near the marine biology labs. Since this is a species none of us have seen, I went with my mother and sister yesterday to see if it might still be around. Migration was still heavy at Sandy Hook. The field south of Gunnison Road near the labs was loaded with sparrows – at least 9 species by my count. Unfortunately, none of the dozens was a Le Conte's, as far as I could tell. It is difficult to be sure that one was not present since the sparrow action was hot and heavy at times.

Sparrows present along Gunnison Road included Song, Swamp, Lincoln's, Savannah, White-throated, American Tree, and Chipping, along with many Dark-eyed Juncos. Even without the Le Conte's or other Ammodramus types, it was delightful to watch so many sparrows yesterday. Getting the chance to watch Lincoln's and Swamp Sparrows was especially rewarding – the first for its relative rarity and the second since it is one of my favorites. In the same area, there were good numbers of Hermit Thrushes, Eastern Phoebes, both kinglet species, and Brown Creepers. Many of the kinglets seemed to be foraging at or near ground level, often in a grassy lawn. Normally I see kinglets higher in the vegetation structure, so I was surprised to see them acting like juncos.

Raptors included several Red-tailed Hawks, at least two Merlins, and a few Sharp-shinned Hawks. Someone reported a Yellow-breasted Chat at the Gunnison lot a day or two ago, but it was either not present or uncooperative today. However, there was an immature White-crowned Sparrow near Battery Gunnison.

Here are a few photos of the autumn foliage on Sandy Hook:

There were very few butterflies around, but I did see a few Pearl Crescents.

Shorebirds at Sandy Hook

There were lots of birders at Sandy Hook yesterday, perhaps inspired by the news of favorable weather for migration. I did not see many warblers (only 5 species), but it was clear that there was substantial movement last night. There were dozens of Yellow-rumped Warblers, particularly along the Fishermen's Trail near the hawk watch bunker. At Plum Island, the birds were changing over to a winter cast – Ruby-crowned and Golden-crowned Kinglets, White-throated Sparrows, and my first Dark-eyed Junco of the fall. Out on the beaches, most of the Laughing Gulls have moved on, and large flocks of Herring Gulls, Ring-billed Gulls, and Great Black-backed Gulls are taking their place. Winter waterfowl are not present in significant numbers yet, but it is only a matter of time until they are.

I enjoyed spending some time with the Sanderlings and Black-bellied Plovers at the end of the Fishermen's Trail. Sanderlings tend to cluster along the ocean's edge. As a wave recedes, they chase it to feed in the newly washed sand, and then they run back up the beach as a new wave breaks. When not feeding actively, they often loaf just a few feet from the waterline, as these Sanderlings are doing.

The dry spit where they were resting cannot have been very wide, perhaps two feet, with water on both sides.

As I was watching and photographing the Sanderlings, five Black-bellied Plovers flew in to join them. The birds all cleared away when a wave (probably amplified by the wake of a passing boat) washed completely over their resting spot.
