Red-naped Sapsucker
Sphyrapicus nuchalis
Striking medium-sized woodpecker of western North America. Long, solid white wing patch helps distinguish it from Downy and Hairy Woodpeckers. Adult male has red cap and throat; females are similar but with white chin; juveniles are messy brownish-gray overall. The namesake red nape is just a small patch and can be difficult to see. Compare with the extremely similar Yellow-bellied Sapsucker, which barely overlaps in range. Note male Red-naped has a more extensive red throat patch with a narrow, broken black border, and the white markings on the back are less extensive and loosely organized into two rows. Head pattern usually separates it from Red-breasted Sapsucker, but beware some hybrids occur. Breeds in montane forest, often with aspens or willows. Descends to lower elevations in winter; occurs in a variety of woodland habitats from the southwestern U.S. to central Mexico. Like other sapsuckers, drills rows of sap wells into tree bark. Listen for irregular drumming (like morse code) and various nasal calls.
Identification
The red-naped sapsucker is a medium-sized woodpecker, measuring 19–21 cm (7.5–8.3 in) long and weighing 32–66 g (1.1–2.3 oz). 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. They have a yellow breast and upper belly. They are black on the back and wings with white bars; they have a large white wing patch. Adult males have a red throat patch; for females, the lower part of the throat is red, the upper part white.
Taxonomy
The red-naped sapsucker is one of four North American woodpeckers in the genus Sphyrapicus. It has no subspecies. First described by Spencer Fullerton Baird in 1858, it was initially thought to be a subspecies of the yellow-bellied sapsucker. However, there are significant genetic differences between this species and the yellow-bellied sapsucker, and the American Ornithologists' Union recognized it as a distinct species in the seventh edition of its North American birds checklist, published in 1998. Genetic analysis has shown that the red-naped sapsucker is a sister species with (and very closely related to) the red-breasted sapsucker, and that these two species form a superspecies with the yellow-bellied sapsucker. All three species are known to hybridize with each other, with hybrids between red-naped and red-breasted sapsuckers proving particularly common.<p>The genus name Sphyrapicus is a combination of the Greek words sphura, meaning "hammer" and pikos, meaning "woodpecker". The specific name nuchalis is a modern Latin word meaning "of the nape". In its common name, "red-naped", refers to the red patch on the back of the bird's head, while "sapsucker" refers to its distinctive method of feeding.

Range and habitat
Their breeding habitat is mixed forests in the Rocky Mountains and Great Basin areas of North America. They nest in a cavity in a dead tree. Other species which nest in tree cavities reuse nests formerly used by these birds. <p>To provide habitat and foraging for woodpeckers, forest management objectives on public land include snag and live tree retention. Numerous studies have shown woodpeckers will readily nest in logged areas as long as some stands are left standing. The drastic change in forest habitat caused by logging and tree retention drastically effects the quality of nesting sites and is detrimental to the red-naped sapsuckers habitat.<p>These birds migrate south and vacate areas at higher elevations.

Behavior
True to their name, and like other sapsuckers, they drill holes in trees and eat the sap as well as insects attracted to it. They sometimes catch insects in flight; they also eat seeds and berries.<p>Red-naped sapsuckers typically lay 3–7 white eggs. The young are altricial, naked, and helpless. The eggs are incubated for 12–13 days and the young are able to fly and leave the nest 25–29 days after hatching.<p>Throughout western North America, red-naped sapsucker (Sphyrapicus nuchalis) nests have been described primarily in trembling aspen (Populus tremuloides) with decay-softened wood. Heart-wood decay is reported to infect the roots of most aspens that red-naped sapsuckers choose to excavate for nesting. Red-naped sapsuckers typically excavate their first cavity relatively close to the ground and over subsequent years make progressively higher excavations. Most (68%) nest trees were live and 75% had broken tops. Western larch (Larix occidentalis) and birch were greatly over utilized compared to their availability.

Other Birds
Bar-breasted Piculet
Picumnus aurifrons
Small, greenish-brown piculet. Light olive brown, with horizontal barring on the breast changing to vertical streaking on the belly, and a black-and-white speckled crown. Males have a yellow forehead patch. Forages singly or in pairs around the midstory and canopy of secondary rainforest, sometimes joining mixed-species flocks with tanagers and other species. Its song is a high, two- or three-note “sweet, sweet,” similar to the songs of other piculets.
Junin Antpitta
Grallaria obscura
Medium-sized, plain antpitta found in a limited area of the eastern Andes in south central Peru. It is uniform brown lacking strong field marks, but the pale eyering helps separate it from the similar Oxapampa Antpitta. Range and voice are also very important for ID. Typical songs include a short “bit-burr” and a series of five or six grating whistles. Inhabits the understory of high elevation forest and is mostly terrestrial, but sometimes perches higher to sing. It was formerly considered a subspecies of what used to be called Rufous Antpitta.
Eastern Yellow Wagtail
Motacilla tschutschensis
Attractive ground-dwelling bird. Slender and long-tailed, bright yellow below with paler throat and grayish-olive back; extremely variable. Tail is black with white outer feathers; often pumps tail up and down while walking on the ground. Young birds lack yellow color, but have distinctive head pattern. Often seen near water. Listen for high-pitched, piercing call note. Common breeder on Arctic tundra from Alaska to Russia; found in grassy and waterside habitats in Southeast Asian wintering grounds and in migration.
