Hello my name is Libby Keen I do Taxidermy as a hobby, I came across this Sparrow Hawk in Feb thanks to a friend. He had this beautiful creature in his freezer for some time when it had an unfortunite accident with his window.

Before I get some glass eyes for it I need to know if its a Male or Female. As age and gender have different eye colours.

Anywho it isn't red/orange on the front to suggest a male, not sure if they just have orange breast in breeding season.
Its 36cm in lengh to suggest a male as there smaller, and he has the slate coloured back to suggest male too. But I thought they had orange/red breast all year, unless this is a immature male?

You can see my confusion, so I will leave it to the pro's I hope you can help me as I will be very grateful.
