The term 'canary relatives' refers to a group of birds in the finch family, which includes the SERIN (6 letters), SERIN (5 letters), SPAIN (5 letters) and tenerife (8 letters). These birds are native to the Canary Islands and other parts of Europe, North Africa and the Middle East. They are small, brightly colored birds with short, conical bills and long wings. The SERIN is the most common species, while the SPAIN is the rarest. The tenerife is the largest of the four species and is found only on the island of Tenerife. All four species are popular cage birds and are kept as pets.
