Our Spring has been so cold and wet . . . plants and trees have been late to flower . . . and thus the caterpillars that warblers rely on for food have been late to emerge.  A couple weeks ago we had dozens of Yellow-rumped Warblers on our suet feeders as they were stressed from lack of food.

It appears now that the Warbler migration has become compressed by the weather.  This morning I went to Hinkley Park in South Portland, Maine and in 90 minutes saw the following warblers:

• Bay-breasted
• Black-and-White
• Black-throated Blue
• Blackburnian
• Blackpoll
• Canada
• Cape May
• Common Yellow-throat
• Magnolia
• Tennessee
• Wilson’s
• Yellow

and Northern Parula

 . . . all basically standing in the same spot.
