Whimbrels and Lark Sparrow, August 22, 2013

Two Whimbrels flew over the east end of Montrose Beach this morning. This was about 6:30. They continued southeast over Lake Michigan and didn’t act like they were going to stop or come back. This is prime time for Whimbrels along Lake Michigan.

Other birds seen at Montrose Beach this a.m. include 9 Semipalmated Plovers, 2 Baird’s Sandpipers, a Lesser Yellowlegs, 2 Sanderlings, single Least and Semipalmated Sandpipers, and a group of about 8 Forster’s Terns.

I went back out in the afternoon and had a Lark Sparrow in the native planting area near the tower. This was most unexpected as Lark Sparrows are very rare at Montrose in the summer and fall.

First Juvenile Herring Gulls

I had my first juvenile Herring Gulls (3) of the year on July 18. I usually start to see juvenile Herring Gulls about one month after the first juvenile Ring-billed Gulls show up, which is around the third week of June. There were also a couple of Semipalmated Sandpipers on the beach, a few Caspian Terns, including a whistling juvenile, and hundreds of dragonflies over the beach, dunes, and meadow.

Common Terns, June 23, 2013

Two adult Common Terns were inside the protected area at Montrose Beach this morning. Both birds flew off to the west after a few minutes and were not seen again. This is a most unusual record. Other birds seen or heard at Montrose this a.m. include a southbound Great Egret, 2 Eastern Wood-Pewees, and a buzzing Dickcissel.

Confusing Sterna Terns

Forster's Terns

Mike Miller photographed these Sterna terns on Montrose Beach in late May. Both birds are Forster’s Terns and I think both are in their third calendar year, that is, they were born in 2011. The top bird has white underparts, a broad white area between the lower edge of the dark cap and bill, and a tail that extends past the tips of the folded primaries. These are Forster’s field marks. The bill also looks stout and the legs look long to me.

The second bird has a gray tail and a white outer web to the outer pair of tail feathers. These are also Forster’s field marks. Except for the dark outer 5 or 6 primaries both birds look like adults, but adult Forster’s Terns in late May should still have silvery white primaries, so that’s why I think they are in their third calendar year. Immature terns molt their primaries earlier than adults and when tern primaries become worn they darken. The dark primaries of these birds are really the only clue that they aren’t fully mature.

Caspian Tern and Yellow-bellied Sapsucker, April 1, 2013

I had a Caspian Tern and Yellow-bellied Sapsucker this morning. Both are new for me for the year. It was very cold today, more like late February than early April. If this is an April Fool’s joke I’m not laughing. A nice warm-up is forecast for the end of the week and weekend. There should be a big push of birds if this happens.
