The yellow-bellied sapsucker has a length of around 19 to 21 centimetres (7 + 1 ⁄ 2 to 8 + 1 ⁄ 4 in), and an average weight of 50.3 grams (1.77 oz), although this can range anywhere from 35 to 62 grams (1.2 to 2.2 oz). The yellow-bellied sapsucker has a wingspan that ranges from 34 to 40 centimetres (13 + 1 ⁄ 2 to 15 + 3 ⁄ 4 in). [10]
Intensive feeding by sapsuckers is a cause of severe tree damage and mortality, with certain tree species more adversely affected by feeding than others. A USDA Forest Service study found that 67 percent of gray birch ( Betula populifolia ) trees damaged by yellow-bellied sapsuckers later died of their injuries. [ 7 ]
In the nineteenth century, the males and females of this sapsucker were believed to be separate species. The female was first described 1852 as Picus thyroideus, and the male was described in 1857 (Newberry) as Picus williamsonii. Baird appropriated the name Sphyrapicus as the genus for both in 1858. In 1873 Henry Henshaw clarified this matter ...
The red-naped sapsucker is a medium-sized woodpecker, [11] measuring 19–21 cm (7.5–8.3 in) long and weighing 32–66 g (1.1–2.3 oz). [12] Adults have a black head with a red forehead, white stripes, and a red spot on the nape; they have a white lower belly and rump.
A sapsucker's tongue is adapted with stiff hairs for collecting sap. Red-breasted sapsuckers visit the same tree multiple times, drilling holes in neat horizontal rows. A bird will leave and come back later, when the sap has started flowing from the holes. Repeated visits over an extended period of time can actually kill the tree. [9]
