I am convinced that the lower bird in the first photo is a juvenile Brown Goshawk. The upper bird's tail does look much squarer and it is probably an adult female Collared Sparrowhawk based on its similar, but slightly smaller, size than the Goshawk. The Goshawk would be a male on size if the upper bird is, in fact, a Collared Sparrowhawk. The tail is notched in the last photo, a Sparrowhawk character.

A note for the unwary. When a Brown Goshawk moults its centre tail feathers the end of the tail appears straight like a Sparrowhawk's. If the bird is a female the size will give it away.

I have forwarded the original email with links to the photos to Stephen Debus for comment.
