Oceanic islands have often been colonized by small groups of individuals dispersing from the nearest mainland, giving rise to insular populations characterized by locally adapted phenotypes and low genetic diversity. Alternatively, due to past geo‐climatic changes, the present‐day distribution of the species may not correspond to that found at the time of the original colonization so that the current mainland distribution may not include the original source area, leading to erroneous…

Colonization patterns and genetic structure of peripheral populations of the trumpeter finch (Bucanetes githagineus) from Northwest Africa, the Canary Islands and the Iberian Peninsula
Aim  This paper has three aims: (1) to reconstruct the colonization history of two peripheral populations of the trumpeter finch (Bucanetes githagineus) presumably originating from the same source,

Evidence of connectivity between continental and differentiated insular populations in a highly mobile species
TLDR
The conservation implications of population structure and connectivity of insular and continental populations of a migratory raptor as determined using genetic tools and satellite tracking are investigated.
Repeated vicariance of Eurasian songbird lineages since the Late Miocene
TLDR
This work examined the possible role of climate‐driven vicariance events in generating avian distributions across much of Eurasia and found a pattern of sister species occurring in adjacent areas that cannot be explained by existing biogeographic barriers.
HISTORICAL DIVERSIFICATION OF MIGRATION PATTERNS IN A PASSERINE BIRD
TLDR
The results show that the interruption of gene flow between migratory and sedentary populations is not necessary for the maintenance of such a polymorphism, and that even the most divergent migratory strategies of a bird species are susceptible to evolution in response to historical environmental changes.
Pronounced Fixation, Strong Population Differentiation and Complex Population History in the Canary Islands Blue Tit Subspecies Complex
TLDR
It is clear that strong genetic drift and low level of concurrent gene flow among populations have shaped complex allelic patterns of fixation and skewed frequencies over the archipelago, however, understanding the population history remains challenging.
Population history, gene flow, and bottlenecks in island populations of a secondary seed disperser, the southern grey shrike (Lanius meridionalis koenigi)
TLDR
Moderate genetic differentiation among populations was found, which largely reflected the shrike's bottleneck history; however, a significant pattern of isolation-by-distance indicated that some gene flow occurs between islands, a useful first step toward understanding how secondary seed dispersal operates over broad spatial scales.
