Three-striped Warbler
Basileuterus tristriatus
Active, often noisy warbler found at lower to middle levels of montane cloud forest. Note the olive upperparts and dark and pale pattern on head. Underpart color and extent of cheek patch vary through its range. Dark stripes on head usually contrast with back, and eyebrow is white, not yellow – these two features help to separate it from other similar warblers in range. Usually seen in pairs or family groups. Typical song begins as a rising trill and then morphs into chaotic chattering.
Identification
The three-striped warbler measures 13 cm (5.1 in) in length. It is mostly olive-brown with a buffy belly and underparts. It has distinct black and white striping on the head and a dark cheek. Male and female three-striped warblers have similar plumages.<p>Their song is a rapid series of squeaky chirps.

Eastern Bearded-Greenbul
Criniger chloronotus
A large greenbul often found in family groups or flocks in forest and forest edge with other bearded-greenbuls. Like all bearded-greenbuls, will sometimes puff out throat feathers. The gray head and chest contrast with the white throat and yellow-green belly. The back is olive-green and the tail is reddish; overall the bird appears to be big-headed and big-billed. Similar to other bearded-greenbuls, but note Eastern Bearded-Greenbul’s distinctive vocalizations, larger size, and contrasting gray chest. Often found by call, which is a haunting, quavering, multi-parted whistle, “huuuur-heeeee.” Other similar variations are sometimes accompanied by chatter.

Cordilleran Canastero
Asthenes modesta
Widespread and often fairly common in the Andes, mainly in fairly open habitats from scrub to bogs and rocky slopes. Often relatively conspicuous, running on the ground with tail strongly cocked and often dipped, or singing from a prominent rock. Plumage rather plain overall with brownish upperparts and dark-centered, bright rusty tail. Favors more open habitats than Sharp-billed and Canyon Canasteros, which hold their tails more loosely and flip them around vs. being more stiffy cocked and dipped. Also note vocal differences.

Black Noddy
Anous minutus
A medium-sized black tern with a tail that appears square or slightly forked. Smaller and darker than Brown Noddy with a shorter tail, thinner bill, and more contrasting white cap. Uniformly black back, wings and tail, and dark legs, except on the main Hawaiian islands where tail and rump are grayish and feet and legs are bright orange. Nests on coastal cliffs, in sea caves, and in trees. More often seen in groups than Brown Noddy. Often seen from shore.
