The longest day and with a spectacular thunderstorm to end it. We are up to 52 mm of rain this month with 10% of this falling this evening in 40 minutes. June onwards really is the rainy season for us.

Sedge warbler

The sedge warblers are continuing to sing very loudly and vigorously from weedy tangles and bramble patches at the sides of the fields and roads. They have a tight schedule. Arrive at the end of April, then two months to get their first brood completely independent (a fairly typical small bird 3 weeks eggs, 2 weeks chicks and then 3-4 weeks feeding fledged chicks). As long as everything goes to plan. But as with most open nesting birds, and even ones like sedge warblers that nest hidden deep in cover, they lose 40% of their nests to predators. So many birds will be trying to renest even as some may be thinking of finishing and starting their moult before returning to Africa in August. It means a staggered season and desperate birds singing right through June and July. Some nesting sedge warblers have it even more complicated, with one male having several females in their territory – they may be the ones that really sing vigorously.
