PostWAIS Bird Week, Continued: Mockingbirds in Northern California (Edward Jajko, USA, 08/03/19 5:07 am)
Apropos of mockingbirds, and jays as well, here in Northern California I rejoice when mockingbirds nest near our house. I love hearing their singing and would swear that they make things up in addition to copying what they hear. I love their midnight serenades. As for California jays, which lack the crest of the Eastern blue jay, I chase them out of the yard and away from the feeder. They are vicious, raucous, and mortal enemies of the mockingbird.
The unfortunately much-parodied song "Listen to the Mocking Bird" dates from 1855. It was a favorite of one A. Lincoln.
JE comments: Blue jays are probably the most aggressive of the small birds found in the US, although the hummingbird is even more bellicose. Good thing they only weigh four or five grams. The Aztec god of war, Huitzilopochtli, takes his name from the hummingbird...with reason.
