There are a lot of young families tucked away in secluded corners in barns and redundant pigsties. The nests have mostly been hidden away in gloomy corners away from the prying eyes of predators who are hunting for a meal, after all it's a time of plenty for the predators too.
At the top is a Jenny Wren's nest and it did recently contain a full complement of young but in the last few days they have all flown the nest for a life in the wild. Below is a Blackbird sitting on the family eggs in a nest that has been built on top of an old and empty anti-freeze container, an odd choice but obviously carefully considered.
These nests are a fine example of sensible building in a dry place so eliminating one problem to rearing their young.
