White-throated Crake
Laterallus albigularis
Small marsh bird, very difficult to see as it creeps through dense grass. Far more easily heard: listen for a loud descending chatter that lasts several seconds. If you are lucky enough to spot one, look for the combination of rich rufous neck and sides of breast, whitish throat, and barred black-and-white flanks. Favors damp pastures and marshes, where it usually stays hidden but occasionally runs through open areas.
Identification
The white-throated crake is 14 to 16 cm (5.5 to 6.3 in) long. Males weigh about 50 g (1.8 oz) and females 45 g (1.6 oz). The sexes are alike. Adults of the nominate subspecies have a white throat and upper breast and a rufous face, sides of the neck, and lower breast. Their crown, nape, and upperparts are olive brown. Their belly, vent, and undertail coverts are barred black and white. Subspecies L. a. cinereiceps has a gray face and L. a. cerdaleus has an entirely rufous head and throat.
Taxonomy
The white-throated crake was for a time treated as a subspecies of the rufous-sided crake (L. melanophaius). As a species in its own right, it has three subspecies, the nominate L. a. albigularis, L. a. cinereiceps, and L. a. cerdaleus.

Range and habitat
The nominate subspecies of white-throated crake is found along the Pacific side of southwestern Costa Rica and Panama and through northern and western Colombia into western Ecuador as far south as El Oro Province. L. a. cerdaleus is found in northern Colombia and extreme northwestern Venezuela. L. a. cinereiceps is found from southeastern Honduras along the Caribbean slope of Nicaragua and Costa Rica and into Panama as far as Veraguas Province. The nominate subspecies has also occurred in Peru as a vagrant.<p>The white-throated crake inhabits a variety of both wet and dry landscapes including marshes, wet grassy fields and pastures, thickets, forest clearings, and the edges of watercourses and ponds. In elevation it ranges from sea level to 1,600 m (5,200 ft).

- Resident species
Behavior
The white-throated crake is generally sedentary but may relocate locally to higher ground during the rainy season.<p>The white-throated crake usually forages in cover but will move into the open at dawn and dusk and during rainy weather. Its diet includes insects, spiders, grass and sedge seeds, algae, and some small fruits.<p>The white-throated crake's breeding season varies geographically. It makes a sperical nest of woven grass stems and leaves with a side entrance, placed in a bush or grass tussock over water or ground. The typical clutch size is two to five eggs.<p>The white-throated crake makes an "[a]brupt, explosive descending trill or churr"; its alarm call is "a sharp 'chip'" note.

Antipodean Albatross
Diomedea antipodensis
Huge albatross of the Southern Ocean. Two subspecies: “Gibson’s” breeds primarily on Auckland Island and ranges at sea around New Zealand and eastern Australia; “Antipodean” breeds mostly on Antipodes and Campbell Islands and ranges mainly across Pacific to Humboldt Current off Chile. Plumage highly variable, starting chocolate-brown with a white face and gradually becoming whiter over many years. Younger birds separated from Southern Royal Albatross by darker tail, brown markings on head and back, and lack of black “lips” on cutting edge of bill. Older birds more difficult to separate; focus on more coarsely marked upperwings, often with conspicuous white patch in center of wing, and lack of black “lips”. Often shows orange stain on cheek, never shown by Southern Royal. Identification from other Wandering-type Albatross is extremely difficult and often presumed by range. Older “Antipodean” often retain complete dark cap, tail, and upperwings.
Orange-fronted Fruit-Dove
Ptilinopus aurantiifrons
A small fruit-dove of mangroves and disturbed forests in the lowlands. Bright orange forehead, white throat, gray chest which extends around the back of the neck, and pale purple spots on the wing. Small flocks often seen flying quickly over mangroves. Superficially similar to Beautiful Fruit-Dove, but Orange-fronted Fruit-Dove is found in more disturbed habitats and has a green rather than yellow belly and no dark red band. Call described as a series of soft “hoo” notes.
Bank Swallow
Riparia riparia
Small and compact swallow, with quick flicking wingbeats. Brown above and white below, with a contrasting dark chest band. Note the relatively long, notched tail and narrow, pointed wings. Breeds in colonies; builds nest by tunneling into sandbanks. Can be seen over any open habitat including fields, marshes, and ponds, often in mixed flocks with other species of swallows. Compare with other small brownish swallows where overlaps occur in its extensive global range.
