This is the 15th year of continuous daily publication for 365Caws. All things considered, it's likely it will be the last year as it is becoming increasingly difficult for me to find interesting material. However, I hope that I may have inspired someone to a greater curiosity about the natural world with my natural history posts, or encouraged a novice weaver or needleworker. If so, I've done what I set out to do.

Spring Beaks
Day 193: One of the happiest moments in my year is when I hear the first "Churp?" of an Evening Grosbeak at the feeder. From that point on, I wait anxiously for the arrival of the flock and the time when the querulous "churping" of porch-parrots outside the window becomes almost constant. Yes, they have arrived and are consuming black-oil sunflower seeds as fast as those great green beaks can crack the shells.
During breeding season (i.e., spring), the beaks of both males and females turn a bright chartreuse. In courting his lady-of-the-moment, the male (right) effects a bobbing dance, sometimes fluttering the wings like a juvenile bird soliciting food. Nest-building is done largely by the female (left) who selects a site in the fork of a branch. Locally, the preferred nest-tree is Douglas Fir, although these birds nest may nest in deciduous trees as well. The female will produce 2-5 eggs (generally 3-4). Incubation is done solely by the female; the male will bring her food. Both parents tend the young who will be ready to fly about two weeks from hatching. During the months they are here, I keep a steady supply of sunflower seed in the feeders to assure the return of the flock next year.
