Technopole 03 June
Today saw possibly the first June waterbird count for Technopole. Four species passed the hundred mark; white-faced whistling duck, pink-backed pelican, black-winged stilt and, much the most abundant, topping 800, little grebe. Looking at the available data up to 2007, this seems to be the largest, or second largest count of little grebe for Senegal. The Critical Sites Network website shows one count in the class of 200-20,000 (counts are not given precisely, but this seems an unusually wide class), also for Technopole. Today’s count is still a long way from the 1% threshold of international importance of 10,000 birds for the resident population south of the Sahara. The breeding dates gathered so far for Senegal suggest this is a non-breeding gathering.
The photo above show that there is a pleasant mix of larger waterbirds: including black herons, eurasian and african spoonbills, yellow-billed storks and african darters. The eurasian spoonbills include a ringed Dutch bird. A young osprey, first seen in mid May and eating a fish both then and today at the edge of the NW lake, proved to have a Latvian ring.
It seems reasonable to assume that this is one of the three birds first seen in sub-adult plumage almost two years ago at Technopole and now in full adult plumage with white tips to the primaries. One wonders where they go when not here and if there have been any breeding attempts.
