Golden-browed Chlorophonia
Chlorophonia callophrys
The blue-crowned chlorophonia is a chunky, short-tailed, stubby-billed bird. It is about 13 cm (5.1 in) long and weighs about 24 g (0.85 oz). The species is sexually dimorphic. Adult males have pale violet-blue crown and nape, under the crown a golden-yellow forehead and wide supercilium, and a turquoise eye-ring. The rest of their face, their throat, and their upper breast are emerald-green. They have a thin turquoise collar under the nape and a thin black and chestnut line under the upper breast. Their upperparts are same shiny green as their face. Voice: The golden-browed chlorophonia's song is a "mournful, single-note whistle" that lasts about a second. It has been written as "koow or keeeu". It also makes contact calls that are "soft nasal notes, e.g. neck, and jip and jup". Its song is "a jumble of short but clear and melodious notes, rather disconnected, all given rather softly". In Costa Rica its local common name is a rualdo.
