most fires have a ledge about 5ft up and youll find the bird on there, dunno what your chim is like maybe different.
The fire service would not really be able to help unless its near the top, wich i doubt, the only equipt they have for pigeon rescue is a ladder, if you think that they may be able to help you then ring your county up on a local line and ask advice, not the 999 number.
i can tell you that derbyshire frs would not charge for somthing like this, your county maybe different.
some fires have a trap door half way up or in the loft or out side.
Think about getting the chimney covered for next time.
This is the reason most fanciers dont have the birds on roof tops.
If my birds are not flying then they are in the loft. the birds dont go on rooftops or chimneys. this only happens if the birds are out a while .
hope you get him down
he will drop down to the light at the bottom
