Effect of brood mixing and survivorship of juvenile Canada geese
Article Abstract:
Some 150 species of birds, including Canada geese, have been shown to practice adoption, with a possibly high cost to the adoptive adults. A study designed to evaluate aggregation behaviour in Canada geese shows that adopted goslings were spatially further from female adults than their natural offspring. It is concluded that adopted goslings will have lower survival rates than natural goslings. Details of the study are presented.

Aggression among female lapwings, Vanellus vanellus
Article Abstract:
A study was conducted on female lapwing aggressive behavior by introducing a female dummy conspecific and a male dummy within a lapwing's nest. Both dummies were attacked by female lapwings, with the female dummy lapwing receiving most of the ground and aerial assaults. Results reveal that the aggressiveness of the female lapwings is due to social monogamy and the preservation of the pair bond with their mates.

Teenage love: the importance of trial liaisons, subadult plumage and early pairing in barnacle geese
Article Abstract:
One-year-old barnacle geese are studied for mate sampling, with variables such as plumage type, size, and the age of sample mates. The generally monogamous birds pair off during their first year, after several trial relationships. The benefits of these trial relationships are graphed according to successful mating after pairing is attained.
