Shorebirds Today: Wisconsin Part 2 (1 Viewer)

Here's part two:

1. A dunlin and 3 unknown birds

2. ?

3. unknown sandpiper?

4. These are obviously american white pelicans. My question is about the 2 birds on the right. They have a big bump above their beaks and was wondering if anyone knew why.

Thank so much

1. Look like Semipalmated Sandpipers
2. Semipalmated Sandpipers again
3. Stilt Sandpiper

I agree with Andrew. That is a small Dunlin for the US!

Agree. Sorry I can't help with the pelicans.

 

[nickderry]

agree with the sandpipers, is the bump perhaps a feather stuck to the bill after preening?

American White Pelicans have a distinct casque on their bills. Not sure if this is sex, age or seasonally related, but its certainly normal.

The bump on the pelicans bill seems to be known as a 'keel' and is apparently seasonal being most pronounced on males in late May, thus probably acts as some kind of mate attracting feature.

Interesting. I have seen many pelicans before but mainly in the fall which would explain why I have never seen any 'keels' before.

Thanks all for looking and helping.

I agree with all, except in the first photo, the sandpiper behind the Dunlin and 3 Semis looks like a Least.
