First image shows the whatever on its leg/feathers that he was worried about, but if you look at the second image where it landed you will see there is lots of bark and other sticky bits off plants. The third show it didn’t effect it able to fly to a wall though you can’t see that side of it to see if it’s still there. Other images my son managed to get did not see this ‘whatever’, so hope it was just a leaf of something like that and has just fallen off. Sue
sorry, don’t know where first image went, it is now the last image, sorry about the muddle. Hope you can work out what I mean
