Looks like it’s just begun. My Rattus was posted in Sept 22 and it’s the only one of my mammals with the tag so far.
When I was filtering for the tag, there’s also fastcast bird - only one done so far and no doubt we can expect a deluge.
FASTCAT bird processing will begin shortly. There’s nearly 100 UK mammal observations tagged with ‘fastcat mammal’ now - and the model has been expanded to include marine mammals.
