You'll need to click the image to enlarge the full 1.2Mb photo and look carefully - very carefully.
Click here to see Saturday evening's post showing four individual photos, taken just afterwards, which show their exact locations and we can find out how well you did at spotting or guessing. To make it more fun (and more of a challenge).
But seriously, a number of you have asked about making donations to keep our project going next year: Nick Brown from Derbyshire Wildlife Trust has just posted details in the blog entry below this one.
And finally, here's an update from late yesterday, left by Andy and Chris M. in comments:
Bitterly cold in Derby this evening but when we arrived on the Cathedral Green at about 7.45pm both adults and 1 juvenile were perched at the top of the east face of the tower. Over the next quarter of an hour, the youngster flew a couple of laps around the Green landing quite well on the tower each time.The adult female flew off at about 8.00pm and after about half an hour of waiting, the second juvenile flew in from the west, lapped around the Silk Mill museum and landed on a gargoyle. Both juveniles are becoming much more confident both in the air and at landing!
