As part of Sunday's April Fool's Day Bird Walk, we challenged participants to find and ID as many as seven bogus birds or bird groupings placed along the Marsh Discovery Trail, including the Upland Sandpiper (in a somewhat wooden pose, above) and the egret species (below).

Four more photos and IDs follow — including one obscure bird from Central America that (not surprisingly) nobody correctly ID'd.

Pink Flamingoes (not to be confused with the movie of the same name).

Belted Kingfisher.

Blue-crowned Motmot (note the paddles).

Northern Pintail. ("Wood Duck" would also have been acceptable.)
