Is there a site or does anyone have tips on nesting profiles? eg. a good place to look for cedar waxwing nests are fruit trees...and robins nesting around homes...sparrows in strip mall signs (that was a joke)....I am particularly interested in blue jay and cardinal nests....and hummingbird nests...I think I found the general location of a hummingbird nest last year based on aerial acrobatics of two males....somewhere in one of my apple trees....
