Witbuik zwaluw: De foto boven is gemaakt door Pascal Dubois in Frans Guyana en de eerste foto's hier net beneden door J.H. Ribot langs de Surinamerivier bij Nieuw Amsterdam en op dezelfde paal een door Stephan Ferrier. Deze vogels vliegen bijna altijd vlak boven water, vooral over de grote rivieren, of over open plaatsen. Ze zijn gemakkelijk te herkennen door het wit in de verder glimmende, donkere vleugels en de witte stuit. Dominiek Plouvier maakte de video van de witbuik zwaluw. |

The 789 reported observations of this bird in Suriname, mainly for the last 50 years up to 2018, have been grouped by month. More birds on one day are counted as one observation. Of course, if the graph should depict the total number of birds seen, the differences between the months could be much more pronounced. | The 13 reported breeding observations 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. |
