City Nature Challenge, this weekend (April 25-7). For those unfamiliar, the City Nature Challenge is a "bioblitz" or citizen science census of the biodiversity in green spaces in urban areas around the world, carried out through the app and org iNaturalist. In NYC, the effort is coordinated by CUNY Prof. Kelly O'Donnell and carried out independently by a host of different organizations and groups in different sites around the five boroughs. with iNaturalist, participants fan out in their chosen venue, and take photos of (non-domesticated, non-ornamental or cultivated) living things they encounter, then upload these to iNaturalist. The data is then available for a wide variety of research projects, from the impact of climate change, to population range shifts to the relationship between socioeconomics and biodiversity, to new species discovery, and has figured in an awesome number of publications. More information is available here: (inaturalist.org/.../city-natur...)... . We have a group of students, faculty and neighbors from Pratt Institute going out on Sunday to Brooklyn's Prospect Park. But, in the interest of getting an early start, I stopped by Ft. Greene Park, yesterday, and encountered a few early-birds. See captions for more info. #nature #NaturePhotography #birds #Wildlife #birding #birdphotography #biodiversity

Blue-headed Vireo foraging on a twig. "A stocky small songbird with medium-length tail and fairly heavy, hooked bill and thick legs (compared to warblers). A moss-green bird with a bluish-gray head and crisp white underparts. The face is set off by clean white “spectacles” and throat. Underparts white, sides greenish yellow. Tail and wings blackish, with two white wingbars." (AllAboutBirds)
Northern Flicker, one of a pair, on a branch. "Flickers are fairly large woodpeckers with a slim, rounded head, slightly downcurved bill, and long, flared tail that tapers to a point. Flickers appear brownish overall with a white rump patch that’s conspicuous in flight and often visible when perched. The undersides of the wing and tail feathers are bright yellow, for eastern birds, or red, in western birds. With a closer look you’ll see the brown plumage is richly patterned with black spots, bars, and crescents." (AllAboutBirds)
Yellow-bellied Sapsucker engaged in some ecosystem engineering as it drills on a tree trunk. "Yellow-bellied Sapsuckers are fairly small woodpeckers with stout, straight bills. The long wings extend about halfway to the tip of the stiff, pointed tail at rest. Often, sapsuckers hold their crown feathers up to form a peak at the back of the head. ellow-bellied Sapsuckers are mostly black and white with boldly patterned faces. Both sexes have red foreheads, and males also have red throats. Look for a long white stripe along the folded wing. Bold black-and-white stripes curve from the face toward a black chest shield and white or yellowish underparts." (AllAboutBirds)
White-throated Sparrow on s twig. "White-throated Sparrows are brown above and gray below with a striking head pattern. The black-and-white-striped head is augmented by a bright white throat and yellow between the eye and the bill, which is gray. You’ll also see a less boldly marked form, known as “tan-striped,” with a buff-on-brown face pattern instead of white-on-black." (AllAboutBirds)
