Great Blue Heron

I am surprised that Vennesland and Butler (2011) in The Birds of North America do not mention that Great Blue Herons yawn. After all, this resource covers most of what is known about the birds of our continent. But I think that is exactly what this heron is doing. We came upon this bird as it slept along Olympia’s Capitol Lake on 10 September 2019. The heron nestled its head under its wing coverts. Unfortunately, the bird woke up before I could capture its image. The heron yawned, but did not fly away.
