Waiting for Warblers

I have been mostly a raptor guy since i started birding 2 and a half years ago. But i am starting to spread tot he passerines. I want to get some good warbler shots, so i need to be perfect. I need to get their calls down pat. I made warbler flash cards just likee i make spanish flash cards. Yellow warbler on front, and sweet sweet so so sweet on the back. I am going to the store to hopefully buy a cd, with bird songs. Then instead of listening to regular music in the shower i will listen to the black throated blue warbler haha. Warbler season is really only a few weeks away and I have a lot of work to do. I have a place I am going where there are the following warblers nesting

1.) Cerulean

2.) Hooded
3.) prarie

4.)yellow

5.)Blue winged

6.) golden winged

7.) black and white

during migration i saw black throated blue and black throated green and chesnt sided warbler too.

The early migrants are on the way though. At a local park yesterday i came up with chipping sparrows, pine warblers calling, a palm warbler, my first osprey, and kestrels, and bluebirds.
