I took my grandchildren to the park this afternoon, and the Tamron 150-600 was great for long distance close-ups of them. Then, there was an aerial dogfight between a kestrel and a crow. It's the third I have seen this month as the brave crows defend their nests. So, here is a collage of their manoeuvres.
