[The results of a research on Lanner in southern Sicily, carried out between 1978 and 2018, are reported. 32 Lanner nesting territories have been taken into account, from sea level up to 1200 m of altitude. Until 2005, there were about 25 nesting pairs in the area; but in the following years there was a steady decline. At least 16 sites have been gradually abandoned because of human persecution and, at a lesser degree, of the interference with the Peregrine falcon, Falco peregrinus, and the Bonelli’s eagle, Hieraaetus fasciatus. At present, the number of Lanner pairs breeding in the study area is around 12. From 120 nesting attempts followed, 216 youngs fledged, with a productivity of 1.80, with breeding success of 1.98, fledging rate of 2.40. Out of 109 nests in which there was egg laying, 90 were successful. Out of successful nests, 11 fledged 1 young (12.2%); 37 nests 2 youngs (41.1 %); 37 nests, 3 youngs (41.1%); 5 nests, 4 youngs (5.6%). The number of pairs that have laid eggs, in relation to the number of the monitored nests, was of 90.8%. The ratio between the number of nests in which youngs were raised and the number of pairs that laid their eggs was 88.1%. The ratio between the number of nests from which youngs fledged and the number of breeding pairs was 93.7%.The number of successfully breeding nests, in relation to the number of monitored nests, was 75%. As regards the diet, birds represent Lanner’s most frequent preys. Out of the 415 preys identified, 383 (92.3%) are made up of birds, 29 (7%) by small mammals, 3 (0.7%) by reptiles. In addition to human persecution, the population of Lanner in Sicily is influenced by interspecific competition, particularly with the Peregrine falcon; but in 2 cliffs, about 1 km long and with a substantial wealth of prey, both falcons have been successfully reproducing for over 10 years].

Population Restoration

Abstract The population of the Peregrine Falcon (Falco peregrinus) in the Czech Republic recovered from a nearly total extinction during the 1960s and 1980s (0­3 breeding pairs) and the first successful breeding after this interval was confirmed in 1995. The increase of the population size accelerated after 2000 and it is still growing despite the limited amount of suitable natural breeding opportunities. There were 89 known pairs in 2016, 70 of them were proven to breed with altogether at least 121 reared young. Several breeding attempts on historical buildings in city­centres were recorded up to 2002 (in Prague and Pilsen), but this breeding habitat was abandoned later. More and more pairs are nowadays breeding on industrial buildings. The first breeding on a power plant chimney, 300m above the ground was discovered in 2010. Moreover, 16 breeding pairs were found on industrial buildings in 2016 (mainly tall chimneys or cooling towers and power­plant buildings), all of them breeding in nest boxes. The colonization of industrial buildings started in western part of the Czech Republic and continues eastwards every year. Currently, the easternmost colonized building is in Mladá Boleslav. We have no recent tree­breeding pairs and all eight published historical cases are at least doubtful. Most of the observed Peregrines ringed abroad came from Germany, indicating a strong influence of German population on restoration of the population in the Czech Republic. Within these recoveries, some of Peregrines were released in the tree­breeding population restoration project in Germany and Poland, but all these birds bred on rocks.

Eggshell Thinning

From measurement of 472 eggs of the peregrine falcon (Falco peregrinus) collected in Australia between 1885 and 1977 inclusive, shells were thinner by 10.4 to 38% after 1947-49 and corresponded with the introduction of DDT into Australia. Victoria seemed to have the greatest mean thinning.
