Abstract Individual migrants often fly detours when travelling between breeding and non-breeding sites, resulting in specific changes in flight directions along a migratory leg. Western European populations of the European Roller (Coracias garrulus), the only member of the roller family of birds to breed in Europe, differ substantially in their predicted flight directions, leading to different hypotheses being suggested for passage areas and non-breeding destinations. In this study we have… 
Disentangling Migratory Routes and Wintering Grounds of Iberian Near-Threatened European Rollers Coracias garrulus
TLDR
The studied populations showed weak migratory connectivity, suggesting the confluence of birds from a wide range of breeding grounds in a restricted wintering area, and is suggested to target on defining precisely key areas for this species and identifying specific threats in them in order to develop an appropriate global conservation programme for the European Roller.
Important areas for the conservation of the European Roller Coracias garrulus during the non-breeding season in southern Africa
TLDR
The results suggest that Rollers from different origins (breeding populations) use separate, but overlapping, wintering areas and may have different habitat requirements, and therefore, population-specific conservation strategies in these areas might be needed to fully protect the species.
Conservation ecology of the European Roller
Among temperate birds, two traits in particular are associated with current population declines; an association with farmed habitats, and the strategy of long-distance migration. The European Roller
Insights into the migration of the European Roller from ring recoveries
TLDR
The first international analysis of ring recovery data in the European Roller Coracias garrulus, a long-distance migrant of conservation concern, demonstrates the complementarity of ring recoveries to direct tracking, providing an insight into the migration of juveniles and non-breeding season mortality.
Unravelling migration routes and wintering grounds of European rollers using light-level geolocators
We used light-level geolocators to track the migratory journey of a globally near-threatened trans-Saharan migrant, the European roller Coracias garrulus, from its breeding grounds in Iberia to its
Ten years tracking the migrations of small landbirds: Lessons learned in the golden age of bio-logging
ABSTRACT In 2007, the first miniature light-level geolocators were deployed on small landbirds, revolutionizing the study of migration. In this paper, we review studies that have used geolocators to
Geographical variation in pace-of-life in a long-distance migratory bird: implications for population management.
TLDR
It is highlighted that life-history traits can vary substantially between populations of a single species with a large latitudinal breeding range, and how knowledge about this variability may be key in anticipating different populations' responses to threats as well as to conservation strategies.
A pan‐European, multipopulation assessment of migratory connectivity in a near‐threatened migrant bird
The extent to which individuals from different breeding populations mix throughout the non‐breeding season (i.e. ‘migratory connectivity’) has important consequences for population dynamics and
Return migration of Common Cuckoos (Cuculus canorus) between breeding grounds in Hungary and wintering grounds in Africa as documented by non-PTT GPS technology
Abstract We tagged 12 adult Common Cuckoos (Cuculus canorus) with non-platform terminal transmitter (non-PTT) GPS-UHF telemetry at their breeding grounds in Hungary. One male and two female Cuckoos

Tracking migration routes and the annual cycle of a trans-Sahara songbird migrant
TLDR
This work tracks the individual migration routes and annual cycles of male Northern Wheatears Oenanthe oenantshe, a trans-Sahara songbird migrant from a German breeding population with light-level geolocators, which wintered in the Sahel zone of western Africa.
Endogenously controlled changes in migratory direction of the garden warbler,Sylvia borin
SummaryGarden warblers breeding in central Europe and wintering in tropical and southern Africa show characteristic changes in flight direction during their fall migration: they initially leave their
Migration of the Common Redstart (Phoenicurus phoenicurus): A Eurasian Songbird Wintering in Highly Seasonal Conditions in the West African Sahel
ABSTRACT. Some species of long-distance migrant birds are thought to follow spatiotemporal patterns of high food availability during the non-breeding season, a strategy termed “itinerancy,” instead
A Palaearctic migratory raptor species tracks shifting prey availability within its wintering range in the Sahel.
TLDR
Contrary to earlier hypotheses of random movements in the Sahelian-wintering quarters, the present study shows that Montagu's harriers visited distinct home ranges, they were site-faithful and tracked seasonal changes in food availability related to previous rainfall patterns, caused by the shifting Intertropical Convergence Zone.
The annual cycle of a trans-equatorial Eurasian–African passerine migrant: different spatio-temporal strategies for autumn and spring migration
TLDR
It is demonstrated the existence of fundamentally different spatio-temporal migration strategies used by the birds during autumn and spring migration, and that songbirds may rely on distinct staging areas for completion of their annual cycle, suggesting more sophisticated endogenous control mechanisms than merely clock-and-compass guidance among terrestrial solitary migrants.
From the Mediterranean Sea to Madagascar: Are there ecological barriers for the long-distance migrant Eleonora’s falcon?
We examined the connection between landscape characteristics and behaviour of a long-distance migratory raptor. Our main goal was to test whether long-distance migratory birds adjust their migration
Strong migratory connectivity and seasonally shifting isotopic niches in geographically separated populations of a long-distance migrating songbird
TLDR
Estimating migratory connectivity of a small Palaearctic long-distance migrant, the common nightingale Luscinia megarhynchos, and comparing resources used in non-breeding areas with resources used at the breeding grounds indicates adaptations to changes in food availability.

TLDR
An evaluation of a number of observed and potential detours and the effects of differences in fuel deposition rates and in transport costs for the profitability of detours indicates that reduction of fuel transport costs may well be a factor of widespread importance for the evolution of detour in bird migration at wide ecological barriers.
