If I have got this right it seems that Blue Sky users who are Dorset birders, or those birders visiting Dorset, would benefit our local birding community by adding both #UKbirding#Dorsetbirds to our posts where relevant. Searching these is easy. Just long press on the hashtag and hey presto 😁

you have that right - the Dorset birds hashtag will also appear inside the ukbirding feed, so no need to use both tags (if it's working as it should)
