The black-thighed grosbeak is a large seed-eating bird in the family Cardinalidae, which is endemic to the mountains of Costa Rica and western Panama.
Region
Central American montane highlands
Typical Environment
Occurs in the mountains of Costa Rica and western Panama, especially along forest edges, clearings, and secondary growth near montane and cloud forests. It adapts well to disturbed habitats, including hedgerows, shade coffee, and highland gardens. Typically forages from the understory to mid-canopy, often at fruiting trees or dense shrubs. Prefers semi-open mosaics rather than deep interior forest, though it will enter forest margins.
Altitude Range
900–2800 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
This large-billed grosbeak is restricted to the highlands of Costa Rica and western Panama, where it frequents forest edges, second growth, and high-elevation gardens. Its massive pale bill is built for cracking tough seeds, but it also takes fruits and insects. The song is a rich, whistled series of phrases reminiscent of other Pheucticus grosbeaks, often delivered from semi-concealed perches.
Temperament
shy and somewhat retiring
Flight Pattern
short rapid wingbeats with direct, purposeful flights between cover
Social Behavior
Usually seen singly or in pairs; small family groups may occur outside the breeding season. Nests are cup-shaped and placed in shrubs or small trees at low to mid-levels. Likely monogamous, with both parents contributing to feeding the young.
Migratory Pattern
Resident
Song Description
A rich, mellow series of whistled phrases, sweet and variable, often compared to other grosbeaks. Calls include sharp metallic chips and soft contact notes given from dense foliage.
