[Tweeters] Birding "Slams"

[B B]

Grand Slams in Baseball, Golf and Tennis are well defined.  Not so much for birding.  This Blogpost details 2 recent Birding Slams for me:  5 Falcon species in a day and the 4 Zonotrichia Sparrow species at a single place - and a "sorta slam" - Four Finch species on the four perches on a feeder at the same time.
