At the park: 88

We bounced back from the dismal 2015.

Wood Duck and Hooded Merganser trend chart

From my final report to the team:

It seems like every year I get this final report put together later and later. At any rate, this was a much more successful nesting year for our Wood Ducks and Hooded Mergansers.

Of our 16 boxes that we monitored, we had 16 nests started. That is, one box had a double brood and only one box this year was not used. Of the 16 nests, 13 were (predominantly) Wood Duck, and three Hooded Merganser. (We often have some eggs from the other species in the nest, which messes up the recordkeeping that I submit to the Cornell Lab.) And of the 16, 13 fledged at least some young, one failed, and two I’m just not sure about. The two questionable boxes are #1 and #3, near the tower. When we checked on 8 May, the evidence indicated predation, but when we visited on 22 May, I saw evidence of membranes, indicating that some eggs had hatched.

So, not counting the two questionable boxes, we have a fledge-to-eggs rate of 70% (114/163) for the Woodies and 91% (31/34) for the Hoodies….

Thanks again, everyone, for the hard work, and we’ll see you in February/March! When it should be colder.
