Hi Jane, It is a problem when you have been regularly feeding the birds, they get so used to food on tap as it were, but I'm pretty sure that if you have a kindly neighbour that would help out then they will return to normal once you are home again. Also it won't be cold weather hopefully at the end of Sept., so the birds will still find plenty of seed etc around.
Lot to learn
Thank you Gaynorsl, I feel more reassured now. This is the first year that we have had so many small birds in the area so I don't want to loose them, they are such a joy to see and help to look after.
