“…different phenotypic plastic in different populations. In general, the first (or mean) arrival date of many, but not all, bird species and populations has advanced across the globe: for instance, in the USA (Zelt et al 2017), Lithuania (Zalakevicius et al 2006), and Australia (Smith & Smith 2012). Furthermore, birds breeding in Croatia have shown a trend towards an earlier arrival -both short-and long-distance migratory species (e.g.…”

“…The variable direction of change in arrival dates between species might be related to migratory travel distance. Neotropical migrants are often divided into short‐ and long‐distance migrants (Lincoln 1935), classified based on whether the species primarily remains within North America (short) or travels annually between North and South America (long; Zelt et al 2017). The ruby‐crowned kinglet, golden crowned kinglet, hermit thrush and myrtle warbler fit the short‐distance definition, and all but the golden‐crowned kinglet significantly delayed their arrival.…”

“…Recent studies indicate that neotropical migrants are able to modify the timing of their migration to some extent as temperatures warm (Bitterlin and Van Buskirk 2014, Usui et al 2017). Many species are arriving earlier on their breeding grounds (Zelt et al 2017), and leaving earlier, or later, in the autumn (Jenni and Kéry 2003, Mezquida et al 2007, DeLeon et al 2011). Although stopover habitats are used by most migratory songbirds, fewer studies have examined long‐term changes in arrival timing at stopover sites as the climate changes.…”

As the climate changes, mismatches in phenology between predator and prey species may become more common. For example, many songbirds rely on short peaks in insect and fruit production at stopover sites during migration. Previous research indicates that migratory songbirds are able to modify their departure and arrival dates to some extent despite their reliance on more stable cues such as photoperiod and more stable endogenous factors. However, insect and plant phenology may shift more rapidly with changing climate, reducing foraging opportunities along migratory routes. To quantify changes in songbird arrival patterns at stopover sites during fall migration we analyzed forty years of banding data in nine passerine species commonly captured at banding stations in southwestern Michigan. Weather data revealed that the region has warmed by nearly 2° (C) over this timeframe. For each species, we assessed annual trends in arrival date and temperature at arrival. To determine whether arrival trends impacted stopover site function we also quantified trends in site use and morning mass gain. Arrival dates advanced significantly in three species, and were delayed significantly in three other species. However, air temperature at arrival increased significantly over time for all nine study species. Over the same time period, site use and the pattern of morning mass gain remained stable or increased for all species. Despite the changing climate and the resulting increase in temperature at arrival for migrants, our data indicate that these stopover locations continue to function as a refueling sites. Nonetheless, we must be wary of thresholds and ecological mismatches that may occur if warming trends continue.

“…The 24-year span of this project should be adequate to detect modern changes in arrival date, because some species in New York began to arrive earlier over a 27-year period [ 27 ]. If birds are timing their arrival to temperature, one should see a relationship between arrival data and temperature-departure from the mean temperature for the month of migration.…”

The Dynamics of Arrivals of Maine Migratory Breeding Birds: Results from a 24-Year Study

This citizen-science project is the first systematic study of patterns of spring migration of Maine migratory birds. A comparison of arrival data from the Maine Ornithological Society from 1899–1911 with the modern data (1994–2017) collected for this study indicated that most species are now not arriving earlier, contrary to the predictions of earlier arrivals in the face of global warming. Arrival was synchronous across the lower two-thirds of the state for most species, although some species showed delayed arrivals along the northeastern coast compared to southern coastal areas. Only thirteen of 81 species are now arriving earlier and seven arriving later. Using quantile regression analysis with three levels of tau, the effect of year, temperature-departure from mean monthly temperature and the North Atlantic Oscillation Index were weak. Most species did not respond to any of these explanatory variables using the modern data. Leaf-gleaners showed the strongest responses. Only four species showed increasing abundance in recent years, an effect that influences detectability and hence could confound interpretation of changes in arrival date.
