Sparrow IdentificationThe house sparrow is less than 15cm long. Males can be identified by the grey crown on their heads, and black throat ‘bib’. Females and young are mostly plain brown.
DescriptionThe House sparrow is a significant pest to the food industry because of the risk of contamination from their droppings and the damage done to packaged goods. House sparrows tend to use the same nest every year, resulting in a build up of nest debris, and insects associated with their nests. Sparrows live for four to seven years, with up to five breeding seasons. The breeding season runs through Spring and Summer, and up to three broods of 4–6 eggs may be laid in this time. . .
