The tree bumblebees in the nest box are an interesting photo challenge. Quite easy to film and photo on the iPhone, but trying to use a zoom lens on the SLR was a different sort of challenge. I’m not sure if the quality is any better, and both the me and the bees found the constant chatter of the lens as it autofocused quite distracting. Manual focus seems the way to go.
The North East Bee Hunt has been great for helping me recognise bumblebees in the garden. You don’t need to know much to be able to distinguish the common bumblebees. I’ve gone from “they’re all just bees” to being able to recognise the ones that come to visit the garden.
