Whilst birders pack their binoculars, telescopes and long camera lenses to photograph the wonderful Neotropical birds at REGUA, we often reflect on why these colourful tanagers are found at different altitudes, as if the bird’s territories are indeed stratified.
In my garden, at low elevation, we often find the Green-headed tanager flying in mixed flocks together with Violaceous Euphonia and Blue Dacnis.
Occasionally a woodcreeper, xenops, ant-tanager and even a White-barred Piculet will share the flittering spectacle as they look for insects between leaves, for small fruit and any other tasty morsels.
However we do not find the mid-elevation Brassy-breasted Tanagers, whose busy flocks are only to be found at the higher altitudes.
Where can we see the Gilt-edged Tanager? Occasionally they will be seen at the very top of the mountains or on the drier leeward slopes of the deciduous Mata Atlántica.
This shows us that these colourful beauties help to indicate the altitude, that tanagers aside from their natural colourful plumages are “stratospheric” in more ways than one.
