Migrating birds at night

Does anyone have any suggestions for learning to recognize calls of migrating birds? I heard some last night, but couldn't see them.

The following was posted on another list. Unfortunately, it's apparently not yet available.
I am looking for passerine night flight calls on tape or CD. Has anyone produced anything on this subject? Can someone recommend something?Bill Evans and Michael O'Brien have been working on just such a thing - hopefully they'll get it done and published soon. Bill Evans works at the Cornell Lab of Ornithology in the Library of Natural Sounds, should you wish to contact him about it.

Hello everyone,
Yesterday, Sept 22, I birded Piper Slough [on Bethel Island], hoping that the overnight thunderstorms had dropped in some interesting birds. There wasn't exactly a fallout but there was a decent number of birds. The highlight wasn't a rare bird but large numbers of a pretty common one. Between 9 and 10 AM I made a lame estimate of 2,265 Tree Swallows, all heading northeast to southwest. Since I was down at the base of the levee I couldn't see what birds were passing by out of view but the numbers of Tree Swallows on the move today must have been immense. I also had well over 100 Barn Swallows.
Migrants on the day included the following: 9 Yellow Warblers, 6 Orange-crowned Warblers, 4 Wilson's Warblers, 1 Pacific-slope Flycatcher, 1 Western Tanager, 2 Willow Flycatchers, 1 Winter Wren, 1 Warbling Vireo. Other interesting things included a fledgling American Goldfinch being fed by an adult, a Swainson's Hawk, 3 Virginia Rails, 33 Forster's Terns, and my first 3 White-crowned Sparrows of the season. I was unable to get good enough looks to figure out which race they represented.
Today, Sept 23, I birded the Jewel Lake area of Tilden Regional Park. It was pretty birdy today with several large flocks of bushtits and chickadees. For those of you who don't spend much time searching for vagrants these are the flocks to leaf through in hopes of a rarity. Today I found only one but any "eastern" bird is good in Contra Costa County.
I found a Red-eyed Vireo on the upper Pack Rat Trail, west of Jewel Lake. The flocks here roam around quite a bit so it is unlikely that you would refind this bird but then again you might find something else. Other birds today included 4+ Hermit Warblers, 6+ Townsend's Warblers, 5 Wilson's Warblers, 3 Swainson's Thrushes (usually scarce in the county in fall, much easier to find as a migrant in spring), 12 Warbling Vireos, 3 Winter Wrens, 4 Black-throated Gray Warblers, 2 Pacific-slope Flycatchers, 4 Yellow Warblers. I also had my first Lincoln's Sparrow (1), Fox Sparrow (2) and Ruby-crowned Kinglets (1) of the fall.
Good luck,
Steve Glover
