Someone recently asked me how I knew so many bird songs (and flowers perhaps). The answer is... one at a time. When you hear a song and then locate the bird, you tend not to forget it. It also helps greatly to accelerate the learning process, to go on a walk with Professor William Coleman with Mid Sussex Ramblers. So when I heard the distinctive song of a Nuthatch in my garden, I knew what I was looking for.
The Blackbird above, carrying a worm and searching for more, must have some young to feed nearby.
Above, high in an oak tree, is what a knew was a Nuthatch even if I could only confirm it with a zoom lens. Once the oak leaves open such birds will be difficult to see.
A house roof is good places to see garden birds like this Chaffinch.
It flew off and was immediately and fleetingly replaced by what looks like a House sparrow.
Greenfinches, thrushes etc., go crazy for the fruits of the Amelanchier canadensis above in the Autumn.
Meanwhile in Spring it is glorious.
