Female (Guatemalan) Residents in Guatemala have a brown crown and whisker stripe. All juveniles, regardless of male or female, have a black malar stripe. We now saw 5 types of woodpeckers in Southern VT. According to field guides, there is no difference in markings between a juvenile Flicker and an adult male Flicker. To protect his mate or territory, birds of the same sex become aggressive toward each other (Palmer and Fowler 1975). My husband and I saw a male bird and 2 females this AM and were able to look it up from your beautiful pics. Two Northern Flicker males in a territorial display from Wikimedia Commons. Central Indiana - July 4, 2008: Juvenile Northern Flicker. Northern Flickers typically excavate nesting cavities in dead or diseased pine, cottonwood, or willow trees. Its two major subspecies, the red-shafted and the yellow-shafted, were formerly separate species until they were merged in the 1980s, though some ornithological organizations still list these birds separately. Northern Flickers have two subspecies: the Red-shafted Flicker (C. a. cafer) of western North America and the Yellow-shafted Flicker (C. a. auratus) of the east and far north. Male flickers recognize females by sight. Aggressive displays such as "bill directing" or "bill poking" are used by flickers. Thank you. Other than a slight size difference, the field guides indicate that a juvenile's plumage has a "softer" appearance, and coloration is duller than the adult. Gilded Flickers of southern Arizona have yellow under the wings and tail while Northern Flickers in the western U.S. have red under the wings and tail. Two very different-looking forms -- Yellow-shafted Flicker in the east and north, and Red-shafted Flicker in the west -- were once considered separate species. Gilded Flickers also have more brown on the crown and nape than Northern Flickers which have more gray on the crown and nape. It’s not where you’d expect to find a woodpecker, but flickers eat mainly ants and beetles, digging for them with their unusual, slightly curved bill. Their ranges are roughly divided by the Rocky Mountains except in the northern boreal forest, where the yellow-shafted range extends west across most of Alaska. So exciting to see new birds.

The breast is light brown to off-white and displays brown/black spots. Here, we stress for the first time to our knowledge, that sex-biased investment in parental care may influence the optimal migration strategies of the sexes. On walks, don’t be surprised if you scare one up from the ground. Both sexes feed the young, which leave the nest after 24 to 27 days. White rump sometimes visible while perched.
The color of the hoods also differs in juvenile magpies: male juveniles have a brown/beige hood that is lighter in color than the dark brown hood of a juvenile female. Both incubate the 5 to 8 eggs for about 11 days, then brood the newly hatched young for about 4 days more. Before breeding season, rival flickers may face off in a display where the boys face each other, bills pointed upward, and bob their heads or chase each other around or through branches of a tree while a prospective female watches.

For some birds, such as northern flickers, plumage differences between sexes are much more subtle.
They went on with this behavior for several minutes until overhead, a large hawk flew, and dampened everyones' spirits!

Male (Yellow-shafted x Red-shafted intergrade) Intergrade individuals usually have a mixture of the plumage markings of Red-shafted and Yellow-shafted birds. When observed from a distance, especially if their heads are up, male and female magpies may appear indistinguishable. Male (Red-shafted) Males in the West have a red whisker while those in the East have a black whisker. Females may chase other female rivals around the trees too. Male. Overall, their plumage is grayish brown, and there is horizontal barring across the back and wings.
