The Manchester peregrine chicks were ringed yesterday, and BBC Manchester was there to catch all the action as an expert from the British Trust for Ornithology (BTO) abseiled from the top of the CIS tower to ring, and collect DNA samples, from the two chicks.
Watch the BBC video, and find out why it's so important to get all this information about the youngsters.
And don't forget, there are still plenty of dates going on across the country - with lots of eggs now hatched and parents busy trying to feed their growing young, you could say it's actually the best time to visit a date near you!
