The distribution of 662 observations of the Golden-winged Parakeet, Brotogeris chrysoptera, in Suriname

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 abundance of the Golden-winged Parakeet in diverse zones is respectively:

coastal zone (blue in picture above): U
northern savanna zone(yellow in picture): C
rainforest zone under 400 m (red in picture): C
rainforest zone above 400m (also red in picture): C
Sipaliwini savanna (yellow in the deep south): C

Where C stands for common, U for uncommon, R for rare and blank if not convincingly reported.

The distribution of these observations for the different months

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.
