Varies occasionally like the last species. (Egg). Pale bluish white, spotted with ash-colour and clove-brown: long. diam. one inch seven lines; trans, diam. one inch and half a line.
Common in all parts of the country. Much attached to churches and other buildings, especially such as are in a ruinous and deserted state. Builds in such situations, as well as in the holes of decayed trees; occasionally in chimnies, and even rabbit-burrows. Nest composed of sticks mixed up occasionally with horse-dung, and lined with wool and other soft substances. Eggs four to six in number. Gregarious like the last species, with which it often associates. Feeds on a great variety of animal and vegetable substances.
