Our spring bird migration is continuing. Today we had our first Blue Grosbeak into our sunflower bird feeder. He then hopped down to have a drink from our tiered bird pond. He had not completed his molt completely, so he wasn’t the most beautiful grosbeak, but was welcomed to our yard anyway.
The Lark Sparrows are still here in great numbers enjoying the platform bird feeder. Their face pattern on this sparrow plus the fan shaped tail with the white band make this one of the easiest to identify of the sparrows.
One interesting observation is that Lark Sparrows walk rather than hop across our bird feeder. If fact, hopping is only used during courtship. During courtship a male Lark Sparrow crouches on the ground, holds his tail up at a 45 degree angle from the ground, spreads the tail feathers to show off the white tips, and then struts with its wings drooping so that the wingtips nearly touch the ground. When the female is receptive, the male gives her a small twig just before copulation.
In our area we have observed Lark Sparrows recycling old Mockingbird and thrasher nests. I have also read reports where the eggs and young of two species are found in the same nest, suggesting that the Lark Sparrow shares the nest with the other bird.
I will continue to report on the spring bird migration here in Portal. Good Birding to all.
