Talk given to Scrooby Gardening Club August 2008
You may see around sixty species of bird in a typical garden in Scrooby, with around one hundred species within a twenty minute walk diameter of the village.
We will cover:
- Equipment which may help you
- How to recognise bird species
- Bird species commonly seen in Scrooby.
If you are interested in taking up bird watching, you should invest in a good set of binoculars. Binoculars with 42mm lens are ideal. Also, the binoculars should be marked Z. This denotes that the lens are further apart than your eyes, yielding the benefit that as the light is gathered to your pupils there is a slight stereoscopic effect which counters the foreshortening effect of magnification. Binoculars with around five times magnification ratio are ideal. Binoculars with greater than eight times magnification are too shaky to be used while held in the hand. Binoculars with less than five times magnification do not let enough light into the lens to enable identification of colour and markings.
To encourage birds to visit your garden, put out peanuts, loose seed, niger seed, and bread. It is not harmful to feed birds year round, as used to be thought. There is a general scarcity of wild food for birds.
There are four cues to recognition of bird species.
Size
When attempting to recognise a bird, size is the first cue. It is useful to think of relative size, rather than an absolute measurement. Try to peg the bird in relation to this scale of bird sizing:
- Swan
- Heron
- Pigeon
- Blackbird
- Sparrow
- Wren
Habitat
Is the bird a tree dweller, or a water bird, for example?
Features
Does the bird have a distinctive feature such as a bright yellow beak or a long tail?
Song
Bird song can be distinctive. Song is particularly common during the breeding season, when birds advertise for a mate, and defend territory.
April 2010: The rooks have returned to their nests in the tree tops above Bawtry Hall. The rookery on South Parade in Bawtry is impressively large, busy and noisy. Pairs of rooks can be seen remaking and re-inhabiting the tangles of sticks of previous years, perched in the uppermost branches of the trees. Some nests are contentious; with paired rooks fighting brutally over the territory, dualling and tumbling through the branches to the ground.
