Scarlet Tanager – 5/8/19
Observer: Paul Lauenstein
Observation Date: 5/8/19
Observation Time: 11:10 a.m.
Observation Location: Moose Hill Audubon Wildlife Sanctuary
Common Name: Scarlet Tanager
Scientific Name: Piranga olivacea
Comments: Scarlet tanagers often play host to eggs of the brown-headed cowbird (male and female shown below), particularly where the forest habitat has been fragmented. When a pair of tanagers notices a female cowbird approaching, they aggressively drive her away. If they don’t notice, the cowbird gets rid of a tanager egg and replaces it with one of her own. The tanagers apparently can’t tell the difference, either before or after the egg hatches, and they raise the imposter along with the rest of their brood.
