Help me identify this bird from its song!

[OnTheRunWithMannyMontana]

Please help as this is driving me mad.

Every year around this time a bird returns to the trees and bushes next to our house. I have never seen it but it has a really distinctive call.

This is going to sound a bit odd but it's a constant tweet tweet tweet tweet that goes on for about a minute and the tweets are a second or two apart, the tweet is always the exact same pitch and volume.

I have been through the RSPB website and can't match it up to any of the bird calls on there!

We are in a semi rural location, on the edge of a housing estate in West Yorkshire next to a lot of farmland and fields and forests. It's as green as the eye can see if that helps at all.

Any ideas?

Yep that's it 100%

Cross posted! Hope you get to see it!
also you might hear the drumming in Spring

Nice one! I’m a keen birdwatcher and see may be a handful a year. They’re not THAT common, at least not around where I live.

Squeaky foot pump, or call sounding like Teacher! Teacher! is a great tit.

I’m lucky - I live near a huge park that turns into wild wood. I see Greater Spotter Woodpeckers every time I go there. Maybe twice a week.

A woodpecker! Oh wow, I've never 'spotted' one.

<sorry>

I'm going to take a punt on Great Tit. There is a bird in my local park that does this really repetitive one note call over and over again. I was walking through earlier and heard it again. It went on and on, paused and then started doing the "teacher-teacher" call that is more commonly known.
My birdwatching friends tell me that if you hear something in a wood and can't identify it, 9/10 times it's a Great Tit.

Duh, just saw you'd identified it.
GSW has a really repetitive single note call. They've just started 'drumming' round my way. As a PP says, they're reasonably common - but they are hard to spot as they tend to turn their heads a lot when calling, scattering sound in all directions!

Just heard my first GSW drumming of the year 😁
