The Comb-crested Jacana, also known as the Lotusbird, has a red fleshy forehead comb, a black crown, back and breast and brown wings. The belly, face and throat are white, and there is a faint yellow tinge around the eye and throat. Both sexes are similar in appearance, but the female is larger than the male, and slightly brighter in colour. In flight, the long legs and toes trail behind the body. Young Jacanas resemble the adult birds, but are rufous to black on the head and nape, and have a rufous-black breast band. The red fleshy comb is much smaller and darker.
Stocky; short-tailed; long spiky crest; upperparts rust, dull sandy-brown with streaks darker on hindneck and mantle; upper -breast more heavily streaked. Photo taken in Al Wathaba Wetland Reserve, Abu Dhabi, UAE
Acanthurus leucosternon is a marine tropical fish belonging to the family Acanthuridae, or surgeonfishes. Its common names are powder blue tang and powder blue surgeonfish. The fish can reach an average size of 23 cm in length. The body has an oval shape and is compressed laterally. Like other surgeonfishes, Acanthurus leucosternon swims with its pectoral fins. The caudal fin has a crescent shape. The fish has a "surgeon's scalpel," an erected part of the spine located at the base of the tail. The mouth is small and pointed in a beak-like manner with tiny and sharp teeth for reaching narrow spaces of food. Its sides are blue; its dorsal fin and the base of caudal fin are yellow; the head is black; the mouth, the throat area, the anal and pelvic fins are white. The pectoral fins are transparent with yellow reflections. The intensity of its blue color shows off if the fish is healthy or not. The fish does not undergo color changes as it matures; as some tangs, surgeonfish and unicornfish do. The powder blue tang, like most fish in the family Acanthuridae family, is herbivorous, eating mostly benthic algae. Acanthurus leucosternon has a diurnal activity. It is solitary, territorial and aggressive with other surgeonfish. In cases where food is plentiful, it may feed in shoals, but in cases of scarcity, it may compete individually for food. It may use its surgeon's scalpel as a defensive weapon
Head, Nape and Abdomen are rufous to chocolate brown in color, red bill. Bright royal blue back and tail with black primaries and secondary tips. White throat to centre of breast in adult. Females seem to have paler underparts.
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.
