Thanks,
I counted 4 limpkins today. Looks like we may have a nesting pair.
Also saw a black ibis. Not the juvenile dark brown; these guys were black.
I'm thinking, by where you live, it must have been a Glossy Ibis. They're actually a shimmering dark purple, but they can look blackish under certain conditions.
Where I live, we have the White-faced Ibis. Very similar in just about all aspects. In fact I've seen many WFIBs this month.
