Migration Monitoring: August 17



Adult female Cedar Waxwing

After the initial burst of activity from starlings and resident breeders, activitiy slowed down considerably at the station. The last week has been so quiet that you could hear a pin drop.

One of our biggest highlights was not even a bird - instead we caught a very interesting dragonfly. It was successfully extracted by Bronwyn Dalziel, and we were lucky to get some great photos before it flew away. It was identified as a Swamp Darner, a species which is quite rare in this region.

Finally, today we had our first real wave of migrants. It is amazing how much faster time passes when you are catching birds! Today we banded 34 birds and recorded 11 new species, bringing our season total to 86 species.

This Baltimore Oriole was one of 6 caught in one net! It was a hatch-year bird, most likely born at TTP this summer. Evidently it has been feeding on honeysuckle berries, which are high in carotenoids - the pigment that produces reds, yellows and that brilliant orange that you can see in this bird. Most of the orioles we catch have the typical yellow plumage.
