[62] Breeding colonies may also edge out those of the red-billed chough, but in turn be ousted by larger corvids such as the carrion crow, rook or magpie. [62] Nests are lined with hair, wool, dead grass and many other materials. [68]

Differences from the nominate subspecies include a larger size, at a length about 500 millimetres (20 in), and more graduated outer tail feathers .
The nest resembles that of the carrion crow, but on the coast, seaweed is often interwoven in the structure, and animal bones and wire are also frequently incorporated. [ 18 ] [ 20 ] The four to six brown-speckled blue eggs are 4.3 cm × 3.0 cm ( 1 + 3 ⁄ 4 in × 1 + 1 ⁄ 8 in) in size and weigh 19.8 g ( 11 ⁄ 16 oz), of which 6% is shell ...
