Phthalate diversity in eggs and associations with oxidative stress in the European herring gull (Larus argentatus)

SUMMARYThis paper presents evidence for the involvement of herring gulls (Larus argentatus) as vectors in the recent outbreaks of Salmonella montevideo in sheep and cattle in Scotland and suggests that the transfer can take place over considerable distances. The breeding area in Scotland of herring gulls which overwinter in N.E. England is remarkably similar to the geographical distribution of the outbreaks. This pattern, together with the feeding behaviour of herring gulls on farmland, the presence of S. montevideo in herring gulls just before their departure from the wintering area and the timing of the return just before the peak of outbreaks are all circumstantial evidence implicating this gull in the outbreaks. The rapid return of these gulls to their breeding areas means that S. montevideo can be transported long distances in one day and raises the possibility that the original source of S. montevideo could have been in N. E. England rather than in Scotland.

Food Conditioning

Young herring gulls (Larus argentatus) are known to emit vocalizations and approach their mew-calling parents when the latter return lo the colony with food for their chicks. In contrast, laboratory-reared young deprived of experience with adults approach and vocalize only rarely lo parental mew calls, although they will respond more strongly to the mew calls of two other species. These results suggest that posthatch experience, such as receipt of food from a calling parent, may be important for the normal development of responses to species typical calls. I tested the effects of food training by exposing young herring gulls, in the laboratory, lo mew calls during feedings. By 7 days of age, responses to herring gull calls increased significantly for young trained with these calls, and the initial tendency for the young to respond selectively to mew calls of the ring-billed gull (L. delawarensis) was reversed. Food training also influenced approach and vocal responses to a visual stimulus (my hand) used to deliver food. Results suggest that approach and vocal responses of young herring gulls may be strongly and adaptively influenced by food conditioning during the first few days after hatching.
