Glossy Ibis with large worm--oops, apparently a hybrid with a large worm
Post note: after uploading these and sending a message to cobirds listserve, I took some time to enlarge the photos further. When I did it was clear that there is facial skin behind this ibis' eye. Per Birds of North America online, Glossy Ibis have "a distinctive edging of pale-blue skin above and below but not continuing around eye,". So this is clearly a hybrid bird.
