Serín Azufrado Crithagra sulphurata

Large olive-green and yellow canary with a big, bulbous bill. Shows a bright yellow rump in flight. Found in a variety of habitats, including woodland, scrub, forest edge, gardens, and fynbos. The cheerful song is a fairly low-pitched mix of repeated trills and “chwee” notes. Similar to grosbeak-canaries, but has a brownish rather than pink bill. Also similar to Yellow-fronted Canary but has a bigger bill, a green rather than black streak below the face, and a green rather than gray nape. Similar to White-bellied Canary but has a yellow belly.
