“…In some instances it seems likely that predator recognition is innate; in fact, Curio (1969, quoted in Kullberg & Lind 2002 reported that wild Geospiza finches living on a predator-free island were able to distinguish between predators and non-threatening animals. Similar results were obtained by Lombardi & Curio (1985) in captive reared zebra finches (Taeniopygia guttata) and by Veen et al (2000) in wild Seychelles warblers (Acrocephalus sechellensis).…”

We studied the nest defence behaviour of common kestrel (Falco tinnunculus) pairs against a mount of either a known predator (the hooded crow, Corvus corone cornix) or a novel predator (the raven, Corvus corax). Both corvids are nest predators, are very similar in shape, but the raven is unknown to kestrels living in the study area. This study aimed to ascertain the existence of possible nest defence behaviour variation in relation to familiarity or novelty of the predator. The crow, the known predator, was attacked more often than the raven, the unknown predator. Males and females, considered separately, displayed a similar response against both predators, but females attacked the crow more vigorously than males. Regardless of predator type, the behaviour patterns indicating higher defensive motivation were performed similarly by both partners and some difference arose only in those indicating a moderate defensive motivation. We conclude that predator recognition is likely learned in this species and that knowledge induces the larger partner, the female, to defend the nest more strongly than the male.

“…The set-up consisted of an aviary (1.4 x 1.5 x 1.8 m) equipped with perches and placed between a window and the screen. The window allowed a free view of the surrounding countryside, an important factor influencing responses specially when birds are caged (LOMBARDI & CURIO, 1985). An opening in the screen allowed the observer to collect data.…”

One-tailed statistical tests are often used in ecology, animal behaviour and in most other fields in the biological and social sciences. Here we review the frequency of their use in the 1989 and 2005 volumes of two journals (Animal Behaviour and Oecologia), their advantages and disadvantages, the extensive erroneous advice on them in both older and modern statistics texts and their utility in certain narrow areas of applied research. Of those articles with data sets susceptible to one-tailed tests, at least 24% in Animal Behaviour and at least 13% in Oecologia used one-tailed tests at least once.They were used 35% more frequently with nonparametric methods than with parametric ones and about twice as often in 1989 as in 2005. Debate in the psychological literature of the 1950s established the logical criterion that one-tailed tests should be restricted to situations where there is interest only in results in one direction. 'Interest' should be defined; however, in terms of collective or societal interest and not by the individual investigator. By this 'collective interest' criterion, all uses of one-tailed tests in the journals surveyed seem invalid. In his book Nonparametric Statistics, S. Siegel unrelentingly suggested the use of one-tailed tests whenever the investigator predicts the direction of a result.That work has been a major proximate source of confusion on this issue, but so are most recent statistics textbooks. The utility of one-tailed tests in research aimed at obtaining regulatory approval of new drugs and new pesticides is briefly described, to exemplify the narrow range of research situations where such tests can be appropriate.These situations are characterized by null hypotheses stating that the difference or effect size does not exceed, or is at least as great as, some 'amount of practical interest'. One-tailed tests rarely should be used for basic or applied research in ecology, animal behaviour or any other science.
