Just a quick post today, but plenty of exciting news!
First and fluffiest, we have our first tern chicks!
Second, we completed our GOMSWG Census, and we have some great numbers. In our colony, we counted 428 nests. After applying a correction factor (essentially an estimation of how many nests we missed) we estimate there to be about 477 tern nests on Metinic this year. That’s an increase of more than 100 nests from last year!
Special thanks to volunteers Frank and Sandy, Interns Megan and Kim, and Refuge Staff Beth, Michael, Brian, and Jay for helping us with our census.
Finally, we picked up all of our species ratio flags (see my previous entry, Egg Enigmas for more information), and came up with an estimate of 89 Common Terns to every 100 Arctic Terns. When we apply this ratio to our total counts, we get 256 Arctic Tern nests and 220 Common Tern nests. Our estimation of Arctic Terns on Metinic has increased more than 100 pairs, or 200 individual birds, from last year. This is especially exciting because Arctic Terns have been struggling in recent years.
Now we just have to wait and see how well all our chicks do!
