One advantage of staying at home is the time it gives to really get to know the birds in our garden habitat. I have watched various species nest building and find myself starting to know individual birds. I start to recognise tiny plumage details which can identify an individual. Now territories are formed, all being well these individuals will remain faithful to our garden. I have started to notice really precise flight lines of different individuals too and regular song posts- not just the same tree, but the same twig, time after time.
A female robin began a new nest in our hedge today. She gathered fallen beech leaves from beneath the hedge. Robins build a substantial base of leaves before adding mosses and grasses and hair to the nest structure. Nests are far from haphazard, they are intricate structures designed for optimum breeding performance. They have to safely contain eggs and young, but they must also regulate temperature efficiently. This would include helping to keep an adult bird warm over extended incubation periods in cool weather. The location of nest site is also crucial, to avoid predation and extreme temperatures.
