Hi,
One of my favourite sites to waste some time is Boredpanda, who have some great photo articles, particular this one:
https://www.boredpanda.com/crap-wildlife-photography/Does the first picture in that link say it was by RA Waterman?

What bad or poorly timed photos have you taken?
I'll start. 6 years ago, nearly to the day, I was on Zuma beach in California (just along from Malibu) and 30-50m away at sea was a humpback whale and 4 dolphins. I reached for my camera, to get this wonderful photo:

Yep, totally mistimed it for the second or two they were all underneath the water. Did not zoom or set burst mode either. Anyone care to critique this?

I have a few more but what photos do the other members have?
