Kiwibit Bird Feeder 2 Pro review: sharp 4K detail, choppy video

The Kiwibit Bird Feeder 2 Pro pairs 4K HDR with phase-detection autofocus and a solar-panel roof, making it a sturdy, low-maintenance way to photograph garden birds. Sluggish video frame rates, a muddled app and subscription-locked species ID stop it from soaring, though.
