Old nest.
I’ve had an infestation of Rats with young.in my garden and called out Pest Control. I don't get over sentimental as i take a pragmatic view in conservation. When this has to be taken i don't get over sentimental and Pest Control where here last week on Monday and did what had to be done and will be returning on Tuesday of this week to see if what they did has been a success. All major conservation organisations in the UK have have had to take similar action if the need arrises including the RSPB etc and also the County Wildlife Trust’s. I know some won't agree. But this has to happen at times I'm afraid as there is no other way. And I'm a Life Member of the RSPB since the early 1970’s, Life Member of the Wildfowl Trust, Life Member of the National Trust, Annual Member of my local Wildlife Trust and also an annual member of the Natural History Society of Northumbria. But when this has to happen i will do this as i have many times over the years and will do again: Sorry if i sound so hard. But that’s the way it is
Hello and welcome PB1 to the forum.
Its good that you've cleaned out the nest box, very soon =, if not already, birds will be looking for places to raise their broods.
