Adult killdeer range in length from 23 – 27 cm (9.06 – 10.63 in) with a wingspan averaging 17.5 cm (6.89 in). The largest ringed plover, killdeer weigh 88 g (3.10 oz) on average. Killdeer have a characteristic large, round head, long tail, long flesh-colored legs, and long wings. The bill is short, dark, and thick. Plumage is brownish-tan on dorsal areas and white on the ventral belly and chest; the neck is also surrounded by a white collar. Two large, dark bands surround the upper breast with an additional band located on the head, spanning both the forehead and the area above the bill and continuing around the back of the head. The tail is brown with a black subterminal band, a white terminal band, and white outer tail feathers. Additional defining plumage characters include a brightly colored red-orange rump that is visible during flight and displays, white wing stripes visible during flight. Appearance does not vary between males and females, although breeding females may have additional brown plumage on the head. Juveniles resemble adults with the exception of buff fringe feathers and the presence of only one neck band
For the developers at New York start-up Networked Organisms, smartphones are the butterfly nets of the 21st Century. Their tool, Project Noah, lets people upload photos of plants and wildlife around them, creating a map of the natural world and contributing to scientific research in the process.
Bespectacled scientists of yore would carry around hefty field guides, made up of hundreds of pages of text and photos. But these days, smartphone owners have a lighter option: an app called Project Noah, which aims to help people identify plants and animals as well as collect data from "citizen scientists" about where certain species are located.
Project Noah enables us to be part of a more focused online community where we can learn more about wildlife around us and contribute to scientific research. It pulls participants into deeper, more meaningful engagement by enabling people to go on “missions” to collectively map changes based on sightings.
A modern invention that may also hold the key to saving species in the future. Project Noah is a global study that encourages nature lovers to document the wildlife they encounter, using a purpose built phone app and web community. In addition to the virtual "collection" of species, Project Noah encourages citizen science by linking up with existing surveys including the International Spider Survey and the Global Coral Reef Monitoring Network.
