The warblers are on the move up from South and Central America, and pass through hearabouts in May, on their way north to breed as soon as the buds begin to pop on the trees and the bugs wake up. Girls might like diamonds but the warblers are God's real living jewels.
The Yellow is the yellowest, and maybe most abundant warbler, with a distinctive "sweet sweeet sweet" call. Found throughout the US during migration. They like to be near wet areas - willows, etc., but they will be everywhere soon.
