Such an annoying bird to photograph. Ubiquitous, but almost always invisible.
A passerine is a bird of the order Passeriformes, which includes more than half of all bird species. Sometimes known as perching birds or, less accurately, as songbirds, the passerines form one of the most diverse terrestrial vertebrate orders: it is roughly twice as diverse as the largest of the mammal orders, the Rodentia.
