I have reported several times about our Nuthatch colour ringing study in Jerry and Barbara's garden at Silverdale. Since September 2015 we have caught a total of 21 Nuthatch coming to their well provisioned feeders. The most birds they see at once on the feeders is usually two.
Numbers recorded each month have varied a little with 12 in December and January, 13 in February and a peak of 15 different birds in March. We rather expected numbers to decline in April but13 were recorded in April and 11 in May. These are minimal numbers as un-ringed birds have seen throughout.
The May figure of 11 included 8 which were regular visitors suggesting four pairs breeding in the surrounding woodland with three others visiting very occasionally possibly birds from further afield tempted by the abundant fare in the feeders.
