Going Head-To-Head

Day 194: The sudden spring influx of birds finds the sparrows going head-to-head for seed and, if at first glance you assumed these two were the same species, look again. Notice that the one on the left is wearing a white bicycle helmet, whereas the one on the right has a "mohawk" hairdo, dyed yellow to demand your attention to detail. Now you've got it! Here we have a White-crowned Sparrow (Zonotrichia leucophrys) and a Golden-crowned Sparrow (Zonotrichia atricapilla), the two Sparrow species most common to my yard. The males of most Sparrow species generally have some obvious colouration which makes it possible to tell them apart. However, the females can present problems even for experienced birders. It takes a bit of practice to train the eye to look for field identification points such as eye stripes, wing bars, beak shape, leg colour, breast markings, etc., but if you keep those things in mind while watching birds in your own yard, you will soon discover that it's easier to tell LBJs and LGBs apart (birder parlance for "Little Brown Jobs" and "Little Grey Birds").
