pigeon update...
none.
i'm getting worried, they haven't been there for a couple of days now. maybe it's because of the rain today, or maybe they are fed up of being stared at and reported on by the sad loser in the flat opposite them. anyway, they aren't there today. i did see them yesterday on another roof (mine). i suspect they have constructed an elaborate system of mirros to monitor my progress and to enable them to hide when they know i'm around. they are fiendish.
in other news... i have got a 'singing' blackbird toy that i plan to play to test its authenticity. i know "Aerial" works in encouraging the birds to sing in retaliation, but will the toy. the trouble with this plan is that blackbirds get up early and i do not.
