TL;DR: Analysis of data on the red-backed shrike Lanius collurio collected in Western Poland during 1983–2000 suggests that the relationship between arrival date and population size needs to be considered in studies of avian migration.
Abstract: Many analyses do not consider the problems associated with the effects of population size on encounter recording. Population size could impact on the detection of bird arrival time as there is a higher probability of observing earlier arrival when the population size is greater and the song activity of birds is increased, as occurs with a larger population. As a case study, we have analysed data on the red-backed shrike Lanius collurio collected in Western Poland during 1983–2000. In this period the red-backed shrike’s return to its breeding sites became significantly earlier whilst the contemporary population size increased significantly. To eliminate linear trends through time we have worked on the standardised residuals from regression of both arrival time and population size on year. The correlation between arrival time and population size residuals was significantly negative, further supporting the link between detection and population size. This finding suggests that, in studies of avian migration and its changes over time, the relationship between arrival date and population size needs to be considered.

TL;DR: The "true" shrikes are a striking group of birds occurring throughout most of the Old World and North America as mentioned in this paper, including the Southern grey shrike and the great grey shrikes.
Abstract: The "true" shrikes are a striking group of birds occurring throughout most of the Old World and North America. This is a comprehensive guide to 31 species of shrike from all over the world. It includes information on distribution, general behaviour, ecology and conservation, as well as on identification features. The author covers the latest taxonomic views on the family, and considers the Southern grey shrike to be a separate species from the great grey shrike.

TL;DR: The Great Grey Shrike count in The Netherlands in 2014-2015 yielded a dataset of 220 individual birds in 168 areas, with multiple counts per individual.
Abstract: Since 2007 every winter a count is organised by Waarneming.nl in order to monitor the dynamics of the Great Grey Shrike populations in The Netherlands in a number of dedicated areas. Volunteer bird watchers select their own area and every winter they count twice, in December and in late January / early February. Also the absence of Great Grey Shrikes was noted (0 counts). The results of these yearly counts are captured in maps that show the presence / absence of these birds (http://waarneming.nl/tel_project_new/gmap/272). For this dataset, covering the winter of 2014 / 2015, in total 220 individual birds were monitored in 168 areas. The dataset contains multiple counts per individual.
