garden, or local area.
Often there are natural reasons for this though, all sorts of factors, including what season it is, changes of
weather and the abundance of nuts and seeds in the country can all have a big effect on what birds are coming
into your garden.
Birds respond in different ways to different weather conditions, cold winters can kill a lot of the birds through
starvation , the smaller the bird, the more likely it is to be affected by cold snaps, but starlings and blackbirds
remain unaffected.
Food availability in May and June can be cruel in deciding how many chicks survive to fledge.
Blue tits and blackbirds are a good example of birds affected by the weather, for a pair of blue tits to succeed
in raising a brood, it needs a plentiful supply of moths and caterpillars, the best caterpillar 'crops' are available
in years when the spring is warm and sunny with low rainfall, and the tits 'breeding' success is quite high.
A particular poor breeding season can result in lower numbers of birds the following season, so you might see

Adult sparrows are struggling to find enough food to feed the chicks in the early stages of their lives
U.K. Bird charity RSPB said measures that boosted insect numbers could also help arrest the sparrows decline.
This included growing deciduous trees and shrubs and cutting insecticide use,in August 2002, the house sparrow
was added to the "Red Data" list of bird species of conservation concern because their decline had been more than
50% in the last 25 years.
While we can't pinpoint one simple cause of sparrows decline, food limitation during the breeding season does
have a negative impact on nestling survival rates.
The RSPB urge people to still put out water and food in the summer and also the colder months,
