It is the final week of Springwatch and Michaela Strachan and Chris Packham are back to update on another busy weekend.

The goldcrests fledged early on Friday morning, followed by four of the 11 blue tit chicks, with the remaining seven leaving the nest in the early hours of Saturday. There is more dramatic news from the blackbirds, where one of the chicks returned to the danger zone over the weekend and fell prey to the little owl after a protracted battle between the parents.

In the farmland there are also new nests, with a second yellowhammer clutch and a reed bunting in the field margins, while the yellow wagtails also fledged over the weekend. A recent study is also brought to light, discussing how we define the value of a species might change the way we think about conserving them.

Also at Sherborne is new guest presenter Patrick Aryee, who takes us through some new camera kit that anyone can build at home with a few simple elements. Lucy Cooke is also back and on the trail of Sherborne's otters, as well as reporting on a project to make a home for this charismatic mammal in Cambridgeshire.

Gillian Burke has moved once more, this time to her home region in Cornwall where she is rock-pooling, meeting some of the toughest creatures in the UK making a living at the intertidal zone. Also on the coast is a new nest - a family of parakeets has set up home in a pub in Thanet, Kent, and we meet this brightest of families for the first time. Show less
