The blue-necked tanager (Stilpnia cyanicollis) is a species of bird in the family Thraupidae. It is found in South America from Colombia to Bolivia. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and heavily degraded former forest. The blue-necked tanager averages 12 cm (4.7 in) in length and weighs approximately 17 g (5⁄8 oz). They have a blue hood and throat. The wing coverts, wing edges, and rump are turquoise to a greenish straw color. The posterior underparts are black, violet, or blue. The juveniles are brownish gray, with a hint of adult coloration. Coloration of adults varies slightly by region. The beaks, legs, and feet are black. The diet of the blue-necked tanager consists of fruits, berries, flower blossoms and insects. Tanagers will pick insects from leaves, or sometimes in flight, but fruit is the major dietary item.
The female builds a cup nest of moss, usually well concealed, and lays an average of 2 white eggs with brown spotting. Incubation is 13–14 days and the chicks fledge after 15–16 days. The male and female feed the nestlings on insects and fruit, and may be assisted by helpers. Wikipedia →

With luck
About 10% of wildlife watchers report a Blue-necked Tanager sighting in Medellín on a given day, based on 526 verified sightings from GBIF citizen-science data. It is the 45th most-seen of the 244 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January, May and October
In those months about 20% of wildlife watchers report a Blue-necked Tanager in Medellín on a given day, against about 10% in February–April, June–September and November–December, the lowest months.

GBIF citizen-science records
It is estimated from how often the Blue-necked Tanager is recorded against all the birds logged in Medellín (526 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
