*SALVIN’S [CANIVET’S] EMERALD Cynanthus (Chlorostilbon) [canivetii]
salvini 7.5–8.5cm. Very small hummer of second growth, woodland and edge,
gardens, overgrown clearings, especially in drier areas. Mainly at low to mid-
levels; tail often fanned slightly while hovering. Distinctive in most of range,
but potential overlap with Garden Emerald unclear; birds with intermediate
characters have been reported from cen. Pacific slope. Male Salvin’s averages
longer, more deeply forked tail than Garden and has reddish bill tipped black.
Female from Garden by reddish base to mandible (can be difficult to see),
diffuse whitish median band on outer tail feathers. SOUNDS: Fairly quiet, gruff
dry cht, often doubled or run into short staccato chatters. STATUS: Uncommon to fairly common on n.
Pacific Slope, to 1500m in Central Valley; spills over locally to adjacent n. Caribbean slope; status on cen.
Pacific slope unclear cf. Garden Emerald. (Guatemala to Costa Rica.)
GARDEN EMERALD Chlorostilbon [canivetii] assimilis 7–8cm. Replaces Salvin’s
Emerald on s. Pacific slope, and similar in habits and habitat, although
favoring more humid areas. Distinctive in most of range, but potential overlap
with Salvin’s Emerald unclear; birds with intermediate characters have been
reported from cen. Pacific slope. Note wholly black bill. Male Salvin’s averages
longer, more deeply forked tail and has reddish bill tipped black; female has
reddish base to mandible, whitish median band on outer tail feathers.
SOUNDS: Fairly quiet dry cht and dry staccato chatters, much like Salvin’s
Emerald. STATUS: Uncommon to fairly common on s. Pacific Slope, locally to
2000m; spills over locally to cen. Caribbean slope; status on cen. Pacific slope unclear cf. Salvin’s
Emerald. (Costa Rica to Panama.)
CROWNED WOODNYMPH Thalurania colombica 10–11cm. Medium-size
hummer of humid forest, adjacent second growth. Feeds low to high, often in
shady understory, but regularly visits feeders in more open situations. Male
distinctive, stunning when colors catch the light, with glittering emerald and
purple plumage, forked blue-black tail. Female distinctive, with bicolored
underparts, small white corners to blue-black tail. Imm. male resembles female
but with emerald patches on breast, tail lacks pale corners. SOUNDS: Fairly hard,
ticking rattled chips, at times run into rapid chatters. STATUS: Fairly common
on both slopes, locally to 1400m. (Guatemala to nw. S America.)
BRONZE-TAILED (RED-FOOTED) PLUMELETEER Chalybura urochrysia
11.5–12.5cm. Medium-large lowland hummer of humid second growth,
Heliconia thickets, forest edge, and shady understory. Mainly at low levels,
where often aggressive, chasing off other hummers and perching in shady
thickets where can be difficult to see well. Note bright pinkish-red feet, rather
long and overall dark tail. Male often looks dark overall; on female note pale
gray tail corners. SOUNDS: Loud, slightly squeaky to low rolled chips, at times
in short rattling or spluttering series; flight call a distinctive sharp pit pit.…Song
a varied short medley of nasal rattles and sharp chips. STATUS: Uncommon to
locally fairly common on Caribbean slope, to 900m. (Honduras to w. Ecuador.)
