Ravens are one of the most intelligent species not only of birds but also in the animal world. These large black passerines hold one of the largest brains among birds. Their intelligence has been documented through multiple studies. For example, as mentioned in Wikipedia: Ravens are one of only four known animals (the others being bees, ants, and humans) who have demonstrated displacement, the capacity to communicate about objects or events that are distant in space or time from the communication. Young, unmated Common Ravens roost together at night, but usually forage alone during the day. However, when one discovers a large carcass guarded by a pair of adult Ravens, he will return to the roost and communicate his find. Their problem-solving ability has been tested in an experiment involving a piece of meat attached to a string hanging from a perch. To reach the food, the bird needed to stand on the perch, pull the string up a little at a time, and step on the loops to gradually shorten the string. Four of five Common Ravens eventually succeeded.This supports the hypothesis that Common Ravens are 'inventors'; that is, they have the ability to solve problems presented to them. They are also known to use "tools" in nature. They regularly hide the food they find if they cannot eat it immediately and return to it later. They have been seen even tricking other bird by making them believe they were caching food in one place to divert the possible thiefs who were observing them. They are also known to make calls to atract predators to a prey so that later they can profit eating on the carcass. They are also known to drop pieces of food in the roads so that they get smashed by cars, to them pick them back. They play with each other and they make their own toys. Finally, Ravens can mimic sounds from their environment, including human speech.

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.
