Table 3.

Levels (median and range) of imidacloprid measured in the crop/gizzard content and the liver of grey partridges (Perdix perdix) and pigeons (Columba palumbus, Columba livia and Columba oenas)

	Crop/gizzard			Liver
	Number of analyses	Number of positive^a results	Median (min–max)^b	Number of analyses	Number of positive^a results	Median (min–max)^b
Grey partridge	46	43 ^c	15.0 (0.9–1706.0)	28	10 ^d	3 (0.6–15.0)
Pigeons	51	51	34.7 (0.4–286.7)	29	16 ^d	1.4 (0.3–43.5)

^ai.e. above the detection limit

^bCalculated only from positive analyses. Values in microgram per gram

^cImidacloprid residues were found in the liver of animals for the three cases below the detection limit

^dFor all individuals for which liver analyses were below the detection limit, imidacloprid residues were found in crop/gizzard, except three pigeons for which crop/gizzard could not be analysed but for which imidacloprid was detected in other individuals from the same incident
