Cobb's wren (Troglodytes cobbi) is a fairly small (12-13.5 cm)
The scientific and common names commemorate Arthur Cobb, an author from the Falkland Islands.[2]
Description
The plumage is brown, greyer on the head and breast and more rufous on the tail. There are dark bars on the
Behaviour
The birds typically inhabit dense stands of
Breeding
The nest is a ball of grass lined with feathers and tussac root fibres. It is built on or near the ground among tussac or in a rock crevice. The eggs are pinkish with small reddish spots, three or four are laid in a clutch. The eggs are laid from early October to December and two broods are probably raised during the breeding season.
Status and conservation
This wren is restricted to small rat-free islands with a population of only 4,500-8000 pairs (1997/1998 estimate). It is fragmented into small populations which could disappear if their islands were colonized by rats or cats. The birds' habit of feeding and breeding at ground level makes them very vulnerable to predation unlike the grass wren which lives higher up and can coexist with predators.
The plight of Cobb's wren was recently brought to broader attention by being featured as
It has been reclassified as least concern in 2017 by the IUCN thanks to the control of invasive rats on nearby islands.[3]
