Common Nighthawk Migration - YouTube Common Nighthawks are nocturnal birds. The female alone displays a brood patch. The migratory patterns of this species are difficult to assess because of the difficulty involved in distinguishing between this and other species of nighthawks that mix in parts of the winter range. They are one of a handful of birds that are known to inhabit recently burned forests, and then dwindle in numbers as successional growth occurs over the succeeding years or decades. Once the chicks have broken out of the shells, the removal of the debris is necessary in order to avoid predators. This display by the male is performed repeatedly until copulation.[4]. The bird was photographed in flight by the Diana Fountain in the royal park by Lewis Newman, who shared his discovery on Twitter. [4], While migrating, these birds have been reported travelling through middle America, Florida, the West Indies,[6] Cuba, the Caribbean and Bermuda,[4] finally completing their journey in the wintering grounds of South America,[6][13] primarily Argentina.

They migrate by day or night in loose flocks; frequently numbering in the thousands,[6] no visible leader has been observed. The northbound journey commences at the end of February and the birds reach destinations as late as mid-June.

I always thought they had a magical way about them in flight, swooping and diving unpredictably yet agile. [4], In the common nighthawk, all bodily plumage and rectrices are replaced in the post-juvenile moult. The only reliable way to distinguish Antillean nighthawk without disturbance is also by the differences in their calls. Common and Antillean nighthawks have a longer outermost primary conveying a pointier wing tip than the lesser nighthawk. The male will roost in a neighbouring tree (the spot he chooses changes daily); he guards the nest by diving, hissing, wing-beating or booming at the sites. Nighthawks are closely related to owls, with similarities in DNA and many morphological ­structures as well as plumage. Long-distance migrant. Often roosts along tree branches or on the ground.
