Hi Bruce,
Thanks so much for the information. That beautiful story about the Buzzards
raising the baby Kestrels made my day:) Its not so hard to believe, after
watching our local crows raise channeled billed cuckoos year after year.
I have been really interested to hear the different responses. Thankyou very
much for them.
Overall, I think the only answer is to somehow take a better picture of her
toes. It is hard to show her size in my pictures, but she is really big
compared to him, easily the size of the grey Goshawk that was around here
for a little while. She is different to him in enough ways to make me wonder
about her. For example, she likes to perch on exposed branches, stoic and
tall in posture,whereas he is more `sparrowhawk- like' and loves to sit
amongst dense folliage. Her voice is very loud and she calls frequently
(maybe she's just pregnant and winey?) His voice is more like a soft
twitter.
Someone asked me (Nikolaas) if I am sure they are mates and not just chasing
each other off. I forgot to mention that they had a juvenile with them until
the end of Autumn, and that they also fly around together, as well as
protect the territory against other raptors, such as the occasional Grey
Goshawk and the Bazas. Its only this week that they've been chasing each
other. Its a lot like how the grey butcherbirds behave when they mate.
I hope I will have more, and better , pictures soon!
Cheers,
beinda
