When scanning images of the portfolio of bird-lens.com it was noticed that the Northern Goshawk is still significantly under-represented . Therefore locations were actively scanned which are known to be frequented regularly by Goshawks. For this purpose sites near wetlands were visited especially in late summer or fall, where many (larger) birds rest and / or moult and are therefore available as prey for inexperienced, young Goshawks. Here, I could see and even photograph a young female Goshawk (Accipiter gentilis) approaching me within a few dozen meters. As a result you can see some pictures of this wonderful Northern Goshawk in flight. So strong and breast -heavy like the bird on the pictures in the gallery, the female Goshawk can be differentiated easily from the Sparrowhawk (Accipiter nisus) by size alone.
Other images were shot from an elevated vantage point in the forest. You need time and patience. But then you see pretty easy that Northern Goshawk breeding pairs are territorial. It was also shown that the nests are evenly distributed in the suitable breeding area. Breeding birds defend the environment of their nest within a certain radius, which should not exceed 1km.
Outside the breeding season, territorial behavior is observed, too. Other raptors as the Common Buzzards (Buteo buteo) shown on the images are vehemently attacked. Especially adult males show a year-round commitment to the nest area and defend their territory. On the other hand young female Goshawks, independently roaming in others territory as shown in the picture apparently penetrate easily into foreign territories.
The Northern Goshawk is about 45 to 67 cm in length and has a wingspan of about 130 cm. The female is larger than the male. The adult plumage is brownish gray on the back and consists of a white chest which is finely barred black. Young birds are brownish until the first moult on the upper side. The barring on the breast is replaced in young birds by a streaking or a line drawing. The stripes can be found Continue reading The Northern Goshawk – aerial shots and more
