[Maine-birds] MACHIAS SEAL ISLAND REPORT


Late summer wanderers and early migrants are picking up daily.
 In this last couple of days I've noted several YELLOW WARBLER; a couple of FLYCATCHER Sp.; 2 LARK SPARROWS; a large influx of RED BREASTED NUTHATCHES; a young COWBIRD; several RED WINGED BLACKBIRDS; a couple of immature warblers believed to be BLACK THROATED GREENS.
I've seen at least one female HUMMINGBIRD per day recently.

Shorebirds are steady but the mix is changing. WIMBRELS & GREATER YELLOWLEGS are beginning to show as TURNSTONES & SEMI-PALM PLOVERS disappear.

1 or 2 EAGLES have been putting in appearances with 1 seen today.

HARRIERS are daily visitors. There are at least 3 hunting the island in the rain on Saturday and 1 or 2 throughout today (Sunday).

PUFFIN numbers are still strong with primarily nice sized HERRING arriving for the youngsters.

GULLS are very numerous and a lot are stalking the colony in search of any wayward youngster or other potential meal. This influx is a perennial event, a sort of clean-up crew. The gulls also stake out the colony in anticipation of the Alcid arrival in the spring.

RAVENS (presumed to be "ours") have returned recently after being almost completely absent through the summer. Seeing and hearing them daily now, although I've always doubted that they stay overnight.

The TERNS are sparse. 2 days ago I saw a couple dozen harrying the Harriers. Today there were never more than 3 at a time.
I believe that there may be 3 young Terns remaining on the island ....... possibly only 2.
I'm surprised that those survive with the island constantly patrolled by Harriers.
There are random Terns over-flying the island most of the time but I expect that very soon the will be a morning flight of several hundred appear, signaling departure. Thereafter, it will be unlikely to spot a Tern here, unless there's still one to fledge.
Last year there was a pair of COMMON TERNS here until the end of August, tending their 2 chicks, the last successfully fledge. 

MONARCH BUTTERFLIES are moving every day. Hard to estimate numbers but I've seen as many as 3 together and it's seldom difficult to see one flitting about the island.
