Pygmy Nuthatch
Sitta pygmaea
Small nuthatch of coniferous forests in western North America. Note dark grayish-brown cap and buffy underparts with grayish sides. Very similar plumage to Brown-headed Nuthatch, but no range overlap. Usually occurs in small flocks high in the crowns of pine trees, often mixed with other songbirds. Listen for cute pips and squeaks.

Measurements:<p>It ranges from southern British Columbia south through various discontinuous parts of the western U.S. (northwest U.S., Sierra Nevada range, southern Rockies, etc.), to central Mexico. It is usually found in pines (especially ponderosa pines), Douglas-firs, and other conifers. Pygmy nuthatches clamber acrobatically in the foliage of these trees, feeding on insects and seeds; less often they creep along limbs or the trunk like bigger nuthatches.<p>Pygmy nuthatches nest in cavities in dead stubs of conifers, lining the bottom of the cavity with pine-cone scales, plant down, and other soft plant and animal materials. They may fill cracks or crevices around the entrance with fur; the function of this behavior is unknown. The female lays 4–9 eggs, which are white with fine reddish-brown spotting. She does most of the incubation, which lasts about 16 days. The young leave the nest about 22 days after hatching.<p>This species is highly gregarious. A nesting pair may have other birds as helpers. Outside the breeding season, this bird wanders in noisy flocks. It also roosts communally; over 100 birds have been seen huddled in a single tree cavity.<p>All plumages are similar, with a warm gray cap, blue-gray upper-parts, and whitish underparts. The only feature not seen in the photograph is a whitish spot on the nape, particularly in worn plumage (summer). Vocalizations are highly varied chirps, peeps, and chattering.<p>This species is very similar to the brown-headed nuthatch of the southeastern U.S. Their ranges have no overlap.<p>The pygmy nuthatch features prominently in the climax of the 2000 film Charlie's Angels, in which Cameron Diaz's character, Natalie, discovers the location of the villains' fortress by identifying the call of the pygmy nuthatch, which she says only live in Carmel, California—though the bird shown is not a pygmy nuthatch, which in any case is found in a much wider range.

Pale-breasted Spinetail
Synallaxis albescens
Small, long-tailed bird that tends to stay hidden. Difficult to see well unless singing, when it can perch more conspicuously. Overall pale gray-brown with rufous wings and crown. Similar to Slaty Spinetail but paler especially on the throat. Found in weedy, tangled undergrowth in fields and edges of secondary growth. Distinctive song: a harsh sneezing “achoo…achoo…achoo” repeated over and over.
Gray Fantail
Rhipidura albiscapa
Small songbird with long, pale-tipped tail, tiny, thin bill. Gray above, pale below, with narrow pale wingbars and a thin black border between white throat and chest. Frequently cocks and fans tail. Subspecies vary in upperparts tone and extent of white in the tail. Inhabits wide range of habitats, very active in foraging, and rarely perches in the same place for long.
Sri Lanka Hanging-Parrot
Loriculus beryllinus
Tiny, short-tailed, bright green parrot. Both sexes show red bill and red rump, while male also possesses a scarlet crown. Typically found in ones or twos in the canopy of forests in the Wet Zone, but also wooded areas outside of that zone. Confined to Sri Lanka, where the extremely small size and short tail make it easily identified from all other parrots on the island. Often given flight call is a metallic “zit-zit-zit”. Can also be given singly, as a drawn out “zeeet”.
