CRIMSON-COLLARED TANAGER Ramphocelus sanguinolentus 19–20cm.
Handsome and distinctive tanager of humid forest edge, adjacent second
growth. Mostly in pairs ranging low to high, mainly at mid-levels; usually
independent of mixed flocks. No similar species in Costa Rica. Juv. duller
overall, crimson areas of adult orange-red. SOUNDS: Piercing whistled ssiiew, and
high thin ssiip, also in flight. Song a slightly jerky, unhurried medley of high,
thin, sweet to slightly squeaky whistled notes, 1–2 notes/sec. STATUS: Uncommon
to fairly common on Caribbean slope, locally to 1500m; spills over locally to
humid foothills of n. Pacific slope. (Mexico to w. Panama.)
SCARLET-RUMPED TANAGER Ramphocelus passerinii 17–18cm. Humid
second growth, forest edge, overgrown clearings, gardens. In pairs or small
groups, mainly at low to mid-levels in leafy foliage, at times with other tanagers;
often visits fruit feeders. Male unmistakable, velvet-black with flame-red rump
often puffed out. Female distinctive, with silver-gray bill, grayish head; Pacific
slope birds have variable orange on breast and rump. Juv. resembles female but
bill duller; adult male appearance attained over a few months in summer, when
patchy birds are commonly seen. Comprises 2 groups that have been treated as
species: Passerini’s Tanager R. [p.] passerinii of Caribbean slope; Cherrie’s
Tanager R. [p.] costaricensis of s. Pacific slope, not separable in adult male plumage. SOUNDS: Slightly nasal
cheht or chay, often repeated in excited chatters; rough shih and lisping chatters, such as ssi-ssi cheh-chéh,
at times repeated every few secs; and high buzzy zzrit. Song a variable short medley of (usually 2–5)
slightly nasal whistled chirps, about 2 notes/sec, at times repeated steadily, such as chiéh’i-wieh chiieh-
wieh..., or simply chíeh-lii...; might suggest a musical House Sparrow. STATUS: Fairly common to common
on both slopes to 1200m, rarely 1900m; both groups may be spreading and range overlap seems likely in
w. Central Valley. (Mexico to w. Panama.)
GENUS TANGARA
(11 species). Classic Tangara are rather small, ‘crown jewel’ tanagers most
diverse in lower foothills; recent molecular work, however, shows that most tanagers traditionally placed
in genus Thraupis (Blue-gray Tanager, etc., p. 410) are embedded within Tangara. Usually in pairs or
small groups in forest canopy, often at fruiting trees with mixed flocks. Voices typically underwhelming:
mostly high thin chips and twitters, more than compensated for by stunning plumages.
GOLDEN-HOODED TANAGER Tangara (Stilpnia) larvata 12.5–13cm.
Humid forest, adjacent clearings, gardens, second growth with taller trees. In
small groups or pairs, mainly at mid–upper levels; often with mixed flocks.
Distinctive adult stunning in good light, with black body, golden hood, violet
and turquoise highlights. Juv. usually with adult, shows ghosting of adult
pattern. SOUNDS: Sharp, fairly hard chipping chik and gruff clipped cheht, which
may be repeated steadily. Song a rapid dry trill, often preceded by a few sharp
chips or cheht notes, cheht cheht ch ssiiiiiiiiir, 1–3 secs. STATUS: Fairly common
to common on both slopes, to 1500m. (Mexico to nw. Ecuador.)
PLAIN-COLORED TANAGER Tangara inornata 12–12.5cm. Humid lowland
forest, adjacent second growth with taller trees, gardens. In small groups or
pairs mainly at mid–upper levels; often apart from mixed flocks. Small size and
rather drab plumage distinctive, blue shoulders often concealed; cf. much larger
Palm and Blue-gray Tanagers. Juv. duller and more buffy, lacks blue shoulder
patch. SOUNDS: High thin sip notes and twitters, at times (song?) in prolonged
series mixed with short trills. STATUS: Uncommon to fairly common on
Caribbean slope, locally to 1000m. (Costa Rica to Colombia.)
