Yellow-billed Cuckoo

September 23, 2022, London, Ontario

I rarely see Yellow-bill Cuckoos.  In the Spring, they can be heard from the treetops well hidden in deciduous trees.  I saw one a couple of days ago but didn't get a good photo.  Today, it was up high in a dead tree preening.  This is the best I've seen a Yellow-billed Cuckoo!  

They are slender, long-tailed birds with a downcurved, yellow lower mandible bill.  Cuckoos eat heavily on caterpillars and other insects.  They winter in South America.
