Summer shines on ospreys

Mrs O is a mobile sunshade

In the scorching heat at the main nest, Mrs O is acting as a mobile sunshade for her two youngsters. Wherever she stands on the edge of the nest, she casts a shadow. Two little osprey bodies just about fit inside of it, keeping out of the glare of the sunshine. They have been seen panting in the heat, and one of the chicks was lying on its side motionless for a worryingly long period of time, which caused concerns that it had been overcome by heat stress. The other chick seemed to be dizzy at times, and stumbled about. It cannot have been comfortable sitting in the hot nest in direct sunlight in last week’s intense heat.

SS has been dutifully returning to the nest with large fish, and both chicks are now being well fed. The food also provides some much needed hydration for the pair. In one comical scene at the nest, Mrs O had fed the chicks and taken a good portion for herself, when SS, who had been dozing at the side of the nest, decided to have his share. Mrs O had to grudgingly give it up to her partner.

Intruder osprey photo-bombs domestic scene

The domestic scene was rudely interrupted during feeding time on 27 June when a cheeky male osprey flew onto the nest perch, causing alarm to the whole family. He had no leg rings, so we couldn’t identify him. He was calling, and dropping and flicking his wings, so SS immediately moved to the side of the nest below him, adopting a defensive posture and flicking his wings in agitation. SS then launched into the air towards him and chased the unwelcome guest away from the nest.

Mrs O casually resumed feeding of the chicks and seemed more than happy that SS could deal with the gate-crasher. It is good to see that their partnership is one of teamwork in their endeavour to raise their young.

Sibling bashing

The chicks are growing well and there is now a substantial covering of emerging feathers, although they are not insulated enough to protect them from being too hot or too cold yet. They are both well fed, but occasionally if the parents leave them alone for a few minutes one of the chicks invariably squares up to the other one and viciously pecks at it. It was really pulling at the skin on its sibling’s back and was being quite brutal, until Mrs O returned and the squabble was instantly squashed.

Stinky nest

The nest has been very messy, often strewn with fish debris after feeding. This has attracted scores of flies which can be seen constantly buzzing around the nest. To address this problem, fresh nesting material has been brought in, and dried grass was added to the bottom of the nest. Mrs O brought in fresh pine shoots and proceeded to have a tidy up and move sticks around. Presumably the pine scent would mask the fish smell and not attract the flies as much – an osprey air freshener minus the aerosol.

Home return

There has been a sighting of a returning Tweed Valley bird with ring number PW3 on 28 June. PW3 was seen flying in the Yarrow valley, near to Dryhope, and then on to St.Mary’s Loch. This bird fledged from a nest in 2016 in the Tweed Valley Project area, and it was spotted on migration just south of Paris on 10 September 2016 during the first migration to leave Scotland. This is the first we have heard about the bird since. It is really good to know that as a returning two year-old, this young osprey has chosen to come home to the Borders.

Pair bonding at the back up nest

We are pleased that at back up no.2 nest, FK0 has paired up with an unringed female. and hes been seen bringing fish for her. They are bonding and have tidied the nest and scraped some of the grass away that had started growing on the top of it due to its vacancy as an unoccupied site this year. FK0 is another returning Borders bird and his partner is an unringed female, quite possibly the widow of the late 8C, as this was her nest site last year.

FK8 is a mum

And finally, saving the best news until last!

FK8 CHICKS

It has been confirmed that FK8 is nesting up north in the Dornoch area and has two chicks. This is the satellite tagged female that fledged from Tweed Valley back up nest no.2 in 2014 and was fitted with a satellite tracker. She spends her winters in Portugal and this is her first brood of chicks. Her chicks will also be fitted with trackers and for the first time we will be able to follow a mother and her offspring.
