Species Biology


Medium-sized game bird with a characteristic orange face in relation to its greyish-brown body, short reddish tail and marked upperwings.

It has a white belly and under tail with a brown belly patch expressed on the male and a smaller or non-existent belly patch on the female.

While it does have the ability to fly, this species will almost always be spotted on the ground unless startled.

A typical Grey Partridge stands at just 30 cm in length with a wingspan of 46 cm. They typically weigh approximately 390 grams. 


This omnivorous game bird feeds on a variety of food items from plant material such as grasses, cereals and leaves to animal material such as insects (mainly the young).


In Ireland Grey Partridge is now associated with the margins of cut-away bogs in Co. Offaly.


This species lays a clutch of 13-16 eggs weighing approximately 14 grams each that will be incubated for a period of 23-25 days.

The young will fledge after 14-16 days.

A typical wild individual will be expected to live for approximately three years, reaching sexual maturity at one year. 

Threats faced

This species was once widespread throughout the country but has since suffered significant declines. This is a direct result of a decline in cereal growing in Ireland (Gilbert, Stanbury and Lewis, 2021).


World distribution(GBIF)

Irish distribution
