What's for dinner?

Yellow warbler with always hungry chicks.
Rondeau Park, Ontario, Canada, June 17, 2019.
Taken with a long lens far from the nest.

Look closely and you will see this is a two tier nest.
The nests of the Yellow Warbler are frequently parasitized by the Brown-headed Cowbird. The warbler often builds a new nest directly on top of the parasitized one, sometimes resulting in nests with up to six tiers.
Setophaga petechia
