Each small square indicates a day with the observation of at least 1 (group) of these birds,
the medium ones at least 4 days of observations and the largest ones 10 or more days.
The color of each square indicates: blue for coastal area, yellow for savanna and red for rainforest.
Not all places in Surinam have been equally often visited by birders, so the distribution of the squares
gives an indication of the whereabouts of the birds, but also of the birders. Some places deep in the south
have no reported bird observations, by experienced birders, within 60 kilometer.

The reported observations of this bird in Suriname, mainly for the last 50 years, have been grouped by month for this illustration. More birds on one day are counted as one observation observation, because the number of birds was not always noted down. Of course if the graph should depict the number of birds seen, the differences between the months are much more pronounced for almost all migrating birds.
Reported breeding of this bird in Suriname.
Most observations are about nest with eggs, some about fledglings,
or feeding at a nest or the building of a nest.
Of the about 5000 nests and eggs found for all species together, about 1/3 comes
from the egg collection of Penard between 1896 and 1905.
For some reason most collecting then was done in the first half of each year, so
the shown distribution does not necessarily reflect
the actual breeding preferences.
The main dry season in Suriname is reckoned
to be from half August to the end of November, the main wet season from half
April to half August, but the the timing of begin and end does vary from year
to year. Around March a second dry season often occurs.
