Despite the homeowner being away for some time, Stead said he did not think the bird could have been trapped in the chimney for long.
“He seemed to regain his strength pretty fast as soon as I released him, so I think he was alright,” he said.
He added: “I’ve rescued a robin before, I’ve rescued a jackdaw or two… unfortunately you do get some dead birds come down too.
“There is nothing wrong with getting a bird guard and stopping the birds nesting in there.”
On its website, the RSPB said, external it was “best to prevent birds nesting in chimneys” as it “reduces the risk of chimney fires, as well as avoiding injury to the birds and damage to their nest”.
The charity added that any active nests must be left alone, but “if there are birds stuck in your chimney that aren’t nesting, you can get them out”.
If a bird was not injured, they could be released outside, it said.
