Which it did late on Thursday. Rain, that is. It rained alot. There was flooding all over the area. Highways were shut down on Friday, rivers overflowed their banks. Etc.
So, why did I think that Tinicum's water level wouldn't be affected. We went this morning with camera, scope, 2 dogs and 4 birdnerds. It was cold - and still blowin' a gale. I promised the girls breakfast at Nifty-Fifty's after the trip which is the only thing that kept them going. Anyway, we certainly didn't see any shorebirds. The water was so high that part of the boardwalk was inaccessible.
We walked around the other way and got to see our first Yellow-rumped Warblers of the fall season and a few terns whirling over the water. We noticed that one tern was much smaller and darker than the others. It was a Black Tern, which we really didn't expect to see at Tinicum. Here are photos - not very good, but we can certainly use them for ID purposes.
Black Tern - notice the gray wings, dark spot on shoulder, and no fork in the tail
Forster's Tern - overall white, black spot around eye, forked tail. It is also much larger than Black Tern
