Food was provided for the birds during the first quarter in 2002 (Q1-2002) but none was provided during the previous quarter (Q4-2001)
The mass of food provided and the observation periods are shown in the Q1-2002 worksheet - the averages being 1.3 kg/wk and 15 mins/day.
The effect of the change on the numbers of birds using the garden can be seen in the table (left) which sets out the average peak number of individuals recorded during each of these periods* and the ratio of these numbers, i.e. the factor by which numbers increased when food was provided.
The number of House Sparrows increased very dramatically, with up to 27 seen together in the garden, whilst previously no more than 2 had been seen actually in the garden. Hedge Sparrows were seen feeding below the feeders where seed had been split, along with Collared Doves and Wood Pigeons towards the end of the quarter. Also, Great Tits, formerly a very infrequent visitor became a very regular visitor but always present in small numbers (never more than 2 together).
* - according to the rules of the BTO Garden Birdwatch scheme; these numbers are much smaller than some of the numbers recorded in the Garden_bird_comparison.xls spreadsheet, because the latter records the total number of individuals seen in and from the garden, therefore including large numbers of birds visiting neighbours gardens or passing overhead.
