1. The vocal performance of different species of songbird was compared by measuring the maximum total sound power produced during normal song. This varied from 10 mW/Kg body weight in the linnet Acanthus cannabina and the whitethroat Sylvia communis to 870 mW/Kg in the song-thrush Turdus philomelos. 2. In comparison, the performance of the chicken Gallus domesticus during crowing was approximately 60 mW/Kg. 3. There was some evidence that performance was related to size in the songbirds as a group, the smaller bird being less effective than the larger. 4. Differences in performance are discussed in relation to the presence or absence of intrinsic muscles in the syrinx and to possible effects of scale on the efficiency of the fundamental sound-producing process.

AbstractTo study the effects domestic cats may have on surrounding wildlife, a complete list was made of 558 items caught in the garden or brought into the house by one cat over 17 years, from 1988 to 2005. The effect on prey populations was assessed by comparing their abundance with the previous 15 years’ population without a cat. On balance, this cat (Cat 1) was clearly beneficial to the native bird species by killing rodents and deterring mustelids. The diet of a second cat (Cat 2) was recorded in the same way from 2006 to 2016. This cat caught half the number of items 148:287, but in the same proportions: house mice (37.8:42.6); ship rats (12.8:12.1); European rabbits (all young) (8.1:6.7); weasels (0.7:0.4); dunnock (12.8:9.2); house sparrow (2.0:3.1); blackbird (2.7:2.5); song thrush (1.4:1.3); European greenfinch (0.7:5.8); chaffinch (0.7:3.3); silvereye (10.1:8.3); New Zealand fantail (2.0:1.0); lizards (8.1:1.7). Despite this, there were significant differences: Cat 2 avoided finches (2:28, P = 0.004), and took a few more lizards (12:5). For both cats, birds apparently formed about a third of their diet: 33.4% and 34.5%, but comparison of the proportion of birds and rodents brought into the house (12:92) and found dead away from the house (49:45) implies that 320 rodent kills may have been missed, being far more difficult to find. As top predators, these cats were clearly beneficial to native birds, and proposed control or elimination may precipitate mesopredator release and a rabbit problem.

Abstract We studied the presence and movements of Song Thrush along the southern Tyrrhenian coast line in the region of Campania, from 2013 to 2016, in order to establish the timing of northward migration. We captured and ringed 150 birds with standardised mist-netting. There was little evidence of migration from the second 10-day period of January, when the trapping began, until the first 10-day period of February. There were no peaks due to the arrival of migrant birds though an increase in captures was recorded during the second 10-day period of February with a very considerable peak during the second 10-day period of March. The mean body mass showed significant increases from the third 10-day period of February, with the highest values recorded in March, also reflected in the accumulation of subcutaneous fat; 91% of subjects with fat scores 3 and 4 were concentrated between the third 10-day period of February and the third 10-day period of March, while the first birds with fat appeared only in the first 10-day period of February. Analysis of several recoveries of thrushes ringed in Campania, in other Italian regions and in other countries, confirms the presence of these birds in Campania in the period between the third 10-day period of January and the third 10-day period of March. The data gathered during the four years of this investigation provide a fairly clear, though not conclusive, picture of the temporal trend of pre-nuptial migration of Song Thrush, which never began before the second 10-day period of February, although it is possible that some birds on migration may be present in the previous 10-day period.

Interspecific Relation

Aggression has important implications for ecological processes and evolutionary behavior strategies. Below there are the data concerning the aggression of blackbird and song thrush in natural conditions and the territories with significant anthropogenic influence on watering places during the nesting period, their relations to other behavior acts, their occupation dynamics during the day and the presence of other species of birds nearby. The interspecific and intraspecific contacts of thrushes are considered. The ratio of aggressive and non-aggressive contacts and the symmetry of interspecific relations (i.e. the ratio of interspecific relation initiated by the individuals of another species) were studied.
