“…In general, variation in migratory strategy is known to differ between individuals from different breeding populations and of different sex and age (Ellegren , Ottosson et al , Scheiffarth et al , Catry et al , Rubolini et al , Maggini and Bairlein ). However, researchers that have addressed the phenology of bird migration in a climate change context typically analyse large scale population trends and do not make a distinction between age, sex or population differences (autumn migration: Sparks and Braslavská , Cotton , Jenni and Kéry , Filippi‐Codaccioni et al , Smith and Paton , Lehikoinen and Jaatinen ; spring migration: Cotton , Gordo and Sanz , Végvari et al , Hüppop and Hüppop , but see Mills , Raini et al , Adamik and Pietruszková , Chambers and Keatley ). In studies that focus on a single species or genus, this distinction is sometimes also not present (Lehikoinen et al , Filippi‐Codaccioni et al , but see Anthes , Barshep et al ).…”

The absence of individually scaled detail is mainly due to the fact that available material does not allow for such distinctions and authors also acknowledge that responses and migratory behaviour may differ between individuals and groups (Lehikoinen et al , Thorup et al , Végvari et al , Lehikoinen and Jaatinen, ).…”

Climate change can influence many aspects of avian phenology and especially migratory shifts and changes in breeding onset receive much research interest in this context. However, changes in these different life‐cycle events in birds are often investigated separately and by means of ringing records of mixed populations. In this long‐term study on the willow warbler Phylloscopus trochilus, we investigated timing of spring and autumn migration in conjunction with timing of breeding. We made distinction among individuals with regard to age, sex, juvenile origin and migratory phase. The data set comprised 22‐yr of ringing records and two temporally separated data sets of egg‐laying dates and arrival of the breeding population close to the ringing site. The results reveal an overall advancement consistent in most, but not all, phenological events. During spring migration, early and median passage of males and females became earlier by between 4.4 to 6.3 d and median egg‐laying dates became earlier by 5 d. Male arrival advanced more, which may lead to an increase in the degree of protandry in the future. Among breeding individuals, only female arrival advanced in timing. In autumn, adults and locally hatched juvenile females did not advanced median passage, but locally hatched juvenile males appeared 4.2 d earlier. Migrating juvenile males and females advanced passage both in early and median migratory phase by between 8.4 to 10.1 d. The dissimilarities in the response between birds of different age, sex and migratory phase emphasize that environmental change may elicit intra‐specific selection pressures. The overall consistency of the phenological change in spring, autumn and egg‐laying, coupled with the unchanged number of days between median spring and autumn migration in adults, indicate that the breeding area residence has advanced seasonally but remained temporally constant.

“…In the last 30–40 yr the autumn migration dates of both short‐distance and long migrants have advanced in several species (Jenni and Kéry 2003, Tøttrup and Thorup 2007, Lehikoinen et al 2010, Filippi‐Codaccioni et al 2011). These observations could be explained by climate warming‐induced advancing in breeding and a fairly constant breeding area residence time.…”

Timing of spring migration and breeding and their interaction with climate change has been widely studied in recent years, but the possible changes in timing of autumn migration have gained less attention. This work focuses on autumn migration and provides the first multi‐species individual‐based study of how hatching date affects the autumn migration date and migration age by using nestling ring data and re‐trappings of the same individuals during the autumn migration at the Hanko Bird Observatory, Finland. We studied three potentially multibrooded passerines (great tit, blue tit and coal tit) and two single‐brooded birds of prey (goshawk, sparrowhawk), all partially migratory short‐distance migrants. Individuals from late broods migrated at a younger age in all tit species and also in hawks the late hatched individuals tended to migrate at a younger age than the early‐hatched individuals. Late‐hatched individuals migrated later than early‐hatched individuals in blue and coal tits, where the latest hatchers represented second brood individuals. Based on our results, the time from hatching to autumn migration is not constant even among individuals of the same population. Our study indicates that climate warming induced advancement of avian breeding may cause changes in the timing of autumn migration through the frequency of second broods.

“…The breeding, stopover, and wintering sites of Common Cranes in the western Palearctic are well known (Prange 2016, Ojaste et al 2020 and their migration phenology has been recorded over several years at different sites (Bautista et al 1992, Filippi-Codaccioni et al 2011, Knudsen et al 2011, Mingozzi et al 2013, Salvi 2016, LPO/Birdlife 2018). However, the drivers of changes in phenology are mostly unknown.…”

Gallocanta lagoon, NE Spain, is one of the main stopover and wintering areas of Common Cranes (Grus grus) migrating through Western Europe. We investigated how the water level of the lagoon where cranes roost, precipitation, and air temperature might have influenced the species' migration and wintering patterns in this area between 1973 and 2018. Over the study period, the mean annual air temperature increased at 0.3 °C per decade. Simultaneously, cranes advanced the spring peak migration date at a rate of 0.37 days/year. Water level and rainfall during spring were also positively correlated with the date of spring migration peak. Because cranes need shallow water to roost, and must drink water from streams because the lagoon is saline, these correlations suggest that low water levels at roosting sites and drinking water shortage may have further accelerated the onset of northward spring migration. The water level was also positively correlated with peak crane numbers in autumn, suggesting that the roosting capacity of the lagoon may limit numbers of cranes that can stopover in the area. We conclude that global warming, variations in the water level of the lagoon, and precipitation during spring have determined changes in the use of Gallocanta as a staging and wintering area by Common Cranes during the last decades. Because climatic models predict further decreases in rainfall and higher temperatures in the area, further advances in the migration phenology of cranes should be expected, which might also have implications for the conservation and management of the species and the study area. Modification de la phénologie de migration des grues associé aux changements climatiques dans le sud-ouest de l'Europe RÉSUMÉ. La lagune Gallocanta, dans le nord-est de l'Espagne, est l'une des principales haltes et aires d'hivernage de la Grue cendrée (Grus grus) qui migre dans l'ouest de l'Europe. Nous avons examiné de quelle façon le niveau d'eau de la lagune où les grues dorment, les précipitations et la température de l'air ont pu influer sur les tendances de migration et d'hivernage de l'espèce dans ce secteur entre 1973 et 2018. Au cours de cette période, la température moyenne annuelle de l'air a augmenté de 0,3 °C par décennie. Simultanément, les grues ont devancé la date de leur pic migratoire printanier au taux de 0.37 jour/année. Le niveau d'eau et les précipitations au printemps ont aussi été positivement corrélés avec la date du pic migratoire printanier. Parce que les grues ont besoin d'eau peu profonde pour y dormir et qu'elles doivent boire de l'eau à partir de ruisseaux étant donné que la lagune est salée, ces corrélations indiquent que de faibles niveaux d'eau aux dortoirs et un manque d'eau potable ont peut-être accéléré encore plus l'initiation de la migration printanière vers le nord. Le niveau d'eau était aussi corrélé positivement avec le nombre maximum de grues en automne, laissant entrevoir que la capacité de rassemblement à la lagune limite sans doute le nombre de grues qui peut s'arrêter dans le sect...
