Holes left by a sapsucker As their name implies, sapsuckers feed primarily on the sap of trees , moving among different tree and shrub species on a seasonal basis. Insects , especially those attracted to the sweet sap exuding from sap holes, are often captured and fed to the young during the breeding season.
Woodpeckers tend to be sexually dimorphic, but differences between the sexes are generally small; exceptions to this are Williamson's sapsucker and the orange-backed woodpecker, which differ markedly. The plumage is moulted fully once a year apart from the wrynecks, which have an additional partial moult before breeding. [8]
Sapsucker feeding can kill a tree by girdling, [27] which occurs when a ring of bark around the trunk is severely injured. [26] Ring shake—spaces between rings of growth in trees—can be a result of sapsucker injury. [28] Certain tree species are particularly susceptible to dying after being damaged by yellow-bellied sapsuckers.
The red-bellied woodpeckers use vocal signals to attract and communicate with potential mates. [13] A low "grr, grr" sound is observed in a pair of woodpeckers from the start of courtship until the end of the breeding season. [13] In an intraspecific conflict, red-bellied woodpeckers usually make a loud "chee-wuck, chee-wuck, chee-wuck" sound ...

The red-breasted sapsucker was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the woodpeckers in the genus Picus and coined the binomial name Picus ruber. [2] The specific epithet is Latin meaning "red". [3]
A male X.p percussus gripping a tree. A medium-sized and colorful bird, the Cuban green woodpecker is similar to a sapsucker in general shape and size. [5] [6] Featuring olive green overparts and yellow, streaked underparts, the Cuban green woodpecker usually appears crested, and features a bright red upper breast, as well as a black chin contrasting a white face and supercilium.
