Dimorphic species. Males are glossy black overall and can appear blue-black in bright sunlight. A broad white patch on the primary feathers is visible in flight. The ragged, pointed crest is often raised. Legs and feet are dark, and the eyes are red. Females are an allover slate or ash gray with fine white edging on all wing feathers. Their wing patches do not contrast as prominently as those of male birds, but they share the same pointed crest and red eyes. Juvenile birds resemble females with the same white wing edging but show a gray-brown plumage and dark orange or brown eyes. As juvenile males mature, their gray-brown plumage may become mottled with black feathers.
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.
