Calling for mummy

This chick and it's (I assume) mother were on a chimney, at a house, near where I live.  The mum was out of shot, but sitting nearby, on another chimney stack, looking like she was thinking 'OK dear, I can hear you, I am still here'.  With a very patient look, but maybe tired, as well.  Photo of mummy seagull is in the extra bit.
