The birds formerly bred on Ascension Island itself, but the colonies were exterminated by feral cats introduced in 1815. The birds continued to breed on a rocky outcrop just off the shore of the island. A program conducted between 2002 and 2004 eradicated the feral cats [67] and a few birds have returned to nest on the island. [68] [69]
Woodcocks migrate at night. They fly at low altitudes, individually or in small, loose flocks. Flight speeds of migrating birds have been clocked at 16 to 28 mi/h (26 to 45 km/h). However, the slowest flight speed ever recorded for a bird, 5 mi/h (8 km/h), was recorded for this species. [15]
They occasionally form large flocks, ranging from 26 to 200 birds. [15] It is also found in forest clearings around rain-filled depressions. It runs about in short spurts and dips forward obliquely (with unflexed legs) to pick up food in a typical plover manner. [16] They are said to feed at night being especially active around the full moon. [4]
The hunt ends as dusk becomes night, and resumes when night becomes dawn. [13] Nighttime feeding (in complete darkness) is rare, [ 4 ] even on evenings with a full moon. [ 13 ] The bird displays opportunistic feeding tendencies, although it may be able to fine-tune its meal choice in the moments before capture.
The night herons are medium-sized herons, 58–65 cm, in the genera Nycticorax, Nyctanassa, and Gorsachius.The genus name Nycticorax derives from the Greek for "night raven" and refers to the largely nocturnal feeding habits of this group of birds, and the croaking crow-like, almost like a barking sound, call of the best known species, the black-crowned night heron.

The European Anglophone name "diver" comes from the bird's habit of catching fish by swimming calmly along the surface and then abruptly plunging into the water. The North American name "loon" likely comes from either the Old English word lumme , meaning lummox or awkward person, or the Scandinavian word lum meaning lame or clumsy.
