Squirrel Cuckoo

Piaya cayana

Very striking and long-tailed bright rusty cuckoo, widespread in tropical lowlands and locally up into foothills. No similar species in Mexico and Central America. Occurs in a wide range of wooded and forest edge habitats. Mostly forages stealthily at mid-upper levels in trees, where can be surprisingly difficult to see. Often seen swooping across roads and eliciting a ‘wow’ reaction. Underside of white-tipped tail feathers is rusty overall in West Mexico, blackish overall in other areas.

This large and extremely long-tailed cuckoo is 40.5–50 cm (15.9–19.7 in) long and weighs 95–120 g (3.4–4.2 oz). The adult has mainly chestnut upperparts and head, becoming paler on the throat. The lower breast is grey and the belly is blackish. The central tail feathers are rufous, but the outer are black with white tips. The bill is yellow and the iris is red. Immature birds have a grey bill and eyering, brown iris, and less white in the tail. It resembles the little cuckoo, but that species is smaller and has a darker throat.<p>There are a number of subspecies with minor plumage variations. For example, P. c. mehleri, one of the South American subspecies, has mainly brown (not black) outer tail feathers. Additionally, the subspecies from Mexico, Central America, and northern and western South America have a yellow eye-ring, but this is red in the remaining part of South America.<p>It makes explosive kip! and kip! weeuu calls, and the song is a whistled wheep wheep wheep wheep.

Common Sandpiper

Common Sandpiper

Actitis hypoleucos

Small bicolored sandpiper which often bobs its tail in a distinctively wagtail-like manner. Plain brown with white underparts; distinguished from bulkier and rounder-headed Green Sandpiper by a prominent white spur at the shoulder. Found in a variety of wetland habitats; breeds on stony ground along rivers and lakeshores, with migrants occurring on muddy and rocky substrates from concrete canal banks to channels in tidal mudflats. Mainly found as singles or in small groups, not in flocks or mixed with other species.

Gray Flycatcher

Gray Flycatcher

Empidonax wrightii

Drab, pale-gray flycatcher with little plumage contrast; very similar to other flycatchers, especially Dusky and Hammond's. Often best identified by unique habit of wagging tail downward. Breeding habitat also distinctive: lower, more open habitat than other flycatchers, usually in sagebrush or open juniper forest. In migration and winter, habitat overlaps more with other flycatchers, but still tends to prefer more open areas. Other subtle differences in appearance include shorter wingtips, longer bill, and paler plumage. Song includes hoarse "chivik" phrase and higher, clearer "pseeoo." Call similar to Dusky. Without an excellent view, sometimes best left unidentified.

Shelley's Starling

Shelley's Starling

Lamprotornis shelleyi

A small dark starling of dry country. The upperparts are iridescent, with a blue sheen on the head and green on most of the wing. Also note the chestnut underparts and the yellow-orange eye. Found in dry thorn savanna and thorn scrub, usually in small wandering flocks, often with other species of starlings. Similar to Hildebrandt’s Starling, but slightly smaller and darker overall, with a deeper rufous belly and a less contrasting green wing. Also reminiscent of Superb Starling, but doesn’t have a white chest band. Gives mewing calls, often in a long, continuous series.
