Sharing the incubation

The incubation period is a ‘not much happening’ sort of time for humans usually, as the ospreys share incubation duty and do a bit of stick or bark fetching. But very sadly at Loch of the Lowes yesterday far too much happened – the male, incubating whilst the female was away, left the nest to see off an aerial threat and a crow seized the opportunity to make off with an egg.  We really feel for the staff and volunteers there.

This unwelcome event could occur at Kielder; Nest 1 in particular has a number of visits by corvids. The ospreys sometimes seem too tolerant, merely shouting rather than one of them chasing the corvid away whilst the other stays tight on the eggs. In the light of yesterday at Loch of the Lowes this caution with both of them staying on the nest is perhaps a safer policy.

The last few days at Kielder have been quiet though – only a chaffinch bobbed around the nest edge today! YA is still doing a good share of incubation. Here is a lovely screenshot captured on Tuesday by Amy at Kielder Castle Cafe when the pair were getting ready to swop.

Yesterday Mrs YA was re-arranging the nest and dragged a stick around, causing YA to duck more than once.

Today was bright and quite mild in the morning, but rain arrived later on. The ospreys will be getting wet over the next few days if the forecast is right.
