This study on the non-breeding ecology of the Whinchat Saxicola rubetra was conducted in central Nigeria from February through April. The core site was at Gwafan (N09°53', E08°57'), an open scrubland located 10 km east of the city of Jos. The density of Whinchats at Gwafan was 0.58 individuals/ ha, almost three times the overall density around Jos. Time budget observations of colour banded Whinchats, including six birds fitted with radio-transmitters, showed that they spent 80% of their time perching, 11% foraging, 7% preening, and 2% flying. The main method of catching insects was a swoop to the ground. There was no change in perching, preening or flying time but the time some Whinchats spent foraging increased towards the end of the study period. GPS positions of individuals showed that all birds held clearly demarcated territories and defended them against neighbours. Aggressive interactions were also recorded between Whinchats and other bird species. Three birds colour-ringed in 2006 returned to the study site in 2007 and one occupied almost the same territory, indicating site fidelity.

Исследования, проведенные на лугах северо-востока Архангельской области в долине реки Пинеги, показали изменения фауны и численности некоторых видов птиц, связанные со значительным сокращением или прекращением сельскохозяйственного использования лугов. Следствием стало сокращение численности или отсутствие полевого жаворонка Alauda arvensis и чибиса Vanellus vanellus на некоторых лугах, ранее используемых как выпасы или сенокосы. Исчезновение дубровника Ocyris aureola не связано с прекращением сельскохозяйственного использования лугов. В то же время, в связи с зарастанием лугов древесно-кустарниковой растительностью, относительно высока численность лугового чекана Saxicola rubetra, камышовой овсянки Schoeniclus schoeniclus, пеночки-веснички Phylloscopus trochilus, чечевицы Carpodacus erythrinus, фифи Tringa glareola, большого улита Tringa nebularia и др. Studies conducted in the meadows of the northeast of the Arkhangelsk Region in the valley of the Pinega River, showed changes in the fauna and abundance of some bird species associated with a significant reduction or cessation of the agricultural use of the meadows. The effect was a reduction in the number or absence of the Skylark Alauda arvensis and the Lapwing Vanellus vanellus in some meadows previously used as pastures or hayfields. At the same time, due to the overgrowing of meadows with tree-shrub vegetation, the numbers of Whinchat Saxicola rubetra, Reed Bunting Schoeniclus schoeniclus, Willow Warbler Phylloscopus trochilus, Common Rosefinch Carpodacus erythrinus, Wood Sandpiper Tringa glareola, and Greenshank Tringa nebularia became relatively high. The disappearance of Yellow-breasted Bunting Ocyris aureola is not related to the termination of the agricultural use of the meadows.
