Middelste Jager: deze grootste Jager komt naar de Surinaamse kust en in april 2014 werd een groep van 20 gezien door Tomas Willems, niet zo ver van de kust (15 km, misschien op de trek). Ze werden in de periode juni tot en met september 2012 regelmatig gezien vanaf een onderzoeksvaartuig op wat grotere afstand van de kust (250 km, Marijke de Boer) De foto's zijn gemaakt door Marijke de Boer in juni 2012 en door Tomas Willems in november 2014. |

The 55 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 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. |
