A pair of Sparrowhawks have bred in my garden for the first time. The garden is well above average-sized at three acres and was an arable field before being well-planted with mainly native trees 25 years ago. This record represents the 35th species to have bred here since I acquired the site in 1987.
Despite my being aware of the species regular presence this spring (mostly by the remains of kills), I did not see the nest until Monday, 16th July. In common with other raptors, it is remarkable just how secretive they become when breeding. The nest was quite difficult to see situated near the top of a Scots pine and the two young were already well-feathered and engaged in wing-flapping exercises when I saw them for the first time. They were both out of the nest and in the surrounding branches this morning, 21st July, and I assume that the reason that there are only two of them reflects the low number of juvenile bird prey items that have been available to the parent birds this year. From the kills plucked on a fence close to the nest, nearly all were juvenile birds and comprised chiefly of Starlings, Blackbirds, Chaffinches, Greenfinches, Goldfinches and Tree Sparrows. A more substantial juvenile Woodpigeon taken just before the young Sparrowhawks fledged was almost certainly killed by the adult female.
Although there is an abundance of bird-feeders near the house which are regularly exploited by Sparrowhawks at all other times of the year, this pair have apparently not raided this area, but seem to have regularly hunted across the the fields in more distant locations. Each time an adult returns to the nest, it is invariably greeted by an abundance of agitated Swallows that seemingly appear from nowhere.
