Robber crow (SciiFii)

The robber crow (Corvus indominus) is a species of crow, most closely related to the American greater crow (Corvus brachyrhynchos), that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests, wetlands, forests, open woodlands, grasslands, shrublands, and scrublands across North America to help boost biodiversity. The robber crow is approximately the size of the almost identical-looking New Caledonian crow (moneduloides) or a little larger (40 centimeters in length). The robber crow's vocalization is described as a soft "waa-waa" or "wak-wak", and sometimes as a hoarse "qua-qua" or "waaaark". The robber crow eats a wide range of food, including many types of insects and other arthropods (some caught in flight with great agility, including night-flying insects which it catches at dusk), eggs and nestlings, small mammals, snails (which it drops from a height onto hard stones), and various nuts and seeds. As its name suggests and like the New Caledonian crow, the robber crow is known to use plant materials to create sticks and leaf tools to capture prey hiding in cracks and crevices. These tools can have naturally occurring barbs, or are sometimes fashioned into hooks by the birds themselves. The tool is inserted into the crack or crevice in logs, branches, stones, or man-made structures, and the prey is either impaled or scoped by the bird's tool or the prey is agitated into biting the tool. The crow then withdraws the tool with the prey still attached, and the crow devours its prey. The nest is usually built in tall, isolated trees, though sometimes smaller specimens are used, depending on availability. The cross supports of telephone poles are also frequently used, and both sexes build the nest. A clutch of 12 eggs is laid from February to May (depending on latitude) and are pale blue spotted with various shades of brown. The eggs are normally covered when the incubatiing female leaves the nest. Incubation is 1819 days and the young are usually fledged by around 45 days. Both sexes rear the young. The conservation status of the robber crow is Least Concern due to successful conservation efforts, the robber crow's wide range and its tolerance to many of the human activities.
