Understanding the habitat use and spatial distribution of wildlife can help conservationists determine high-priority areas and enhance conservation efforts. We studied the wintering habitat use, preference, and utilization distribution of two crane species, that is, the black-necked crane (Grus nigricollis, Przevalski, 1876) and common crane (Grus grus, Linnaeus, 1758), in Huize National Natural Reserve, Yunnan–Guizhou Plateau, southwestern China. Line transects indicated that anthropogenic farmland habitat was highly utilized and was positively selected by both crane species (>90% of flocks observed for both species). Black-necked cranes preferred marshland in spring (February and March) but avoided grassland during the entire wintering period, whereas common cranes avoided both marshland and grassland throughout the entire period. The two cranes species had communal nightly roosting sites and separate daily foraging sites. Black-necked cranes were distributed within two km (1.89 ± 0.08 km) of the roosting site, covering an area of 283.84 ha, with the core distribution area encompassing less than 100 ha. In contrast, common cranes were distributed far from the roosting site (4.38 ± 0.11 km), covering an area of 558.73 ha, with the core distribution area encompassing 224.81 ha. Thus, interspecies competition may have influenced the habitat preference and spatial distribution divergence of these two phylogenetically related species. This study should help guide habitat management as well as functional zoning development and adjustment in the future. Based on our results, we recommend restoration of additional wetlands, retention of large areas of farmland, and protection of areas that cranes use most frequently.

Understanding habitat use and spatial distribution of wildlife could help conservationists determine high-priority areas and enhance conservation efforts. In this study, we studied habitat use, preference and utilization distribution of two Gruidae species (Black-necked Cranes Grus nigricollis and Eurasian Cranes G. grus) in Huize National Natural Reserve, Yunnan-Guizhou Plateau, SW China. Line transect method indicated that the anthropogenic habitat of farmland was utilized the most by these two species (>90% of flocks observed for both). But Black-necked Cranes preferred marsh to farmland and grassland while Eurasian Cranes favored grassland in our study. Nearly all the Black-necked Cranes (99.30% of the flocks observed) utilized habitats in the core area of the reserve, covering an area of 283.84 ha close to the common roost. Eurasian Cranes were mostly (55.39% of the flocks observed) distributed in the buffer zone with higher elevation and further distance to the roost, covering an area of 558.73 ha. We believe that our findings could help guide habitat management, functional zoning planning and adjustment in the future. According to our results, we recommended restoration of more wetlands, retain large areas of farmland, and protect the areas that cranes use most frequently.

In many bird species juvenile inexperience drastically reduces their survival, and parents must provide for them. I tested whether time budget and habitat use in adult wintering Common Cranes (Grus grus) in dehesas (pastoral woodland) of western Spain were affected by the presence of juveniles. Juvenile cranes devote less time to vigilance and spend more time feeding than adults in dehesas. Likewise, juveniles are involved in fewer aggressive encounters than adult cranes. Contrary to expectation, adults accompanied by juveniles devoted the same amount of time to vigilance and feeding and had the same intake rate than adults without juveniles in attendance. However, adult cranes with offspring in attendance were involved in more aggressive encounters than adults without juveniles in attendance when both adult groups were involved in large flocks. In contrast, when adults accompanied by juveniles were in small flocks they were involved in fewer aggressive encounters than adults without juveniles. I also detected a differential use of dehesas by adult cranes that was linked to juvenile presence and explained by the vulnerability of juvenile cranes in intraspecific social relationships. Adults with juveniles in attendance preferred dehesas with livestock where flock sizes were smaller than those in dehesas without livestock, and therefore where they might reduce the number of aggressive encounters with other cranes.

SummaryGrallaria antpittas are a group of little known birds from the understorey of humid forests of the tropical Andes, with several species having very narrow distributions. At Ucumari Regional Park, which protects the Otún River watershed in the Central Andes of Colombia, five species occur sympatrically at 2,400 m, including the recently rediscovered G. milleri, of which this is the only known population. We studied the patterns of altitudinal distribution, habitat use and abundance of the five species in the park. We found altitudinal segregation at a local scale, with two species, G. ruficapilla and G. squamigera, found at lower elevations (1,800–2,500 m) and two other species, G. nuchalis and G. rufocinerea, at higher elevations (2,400–3,000); G. milleri was recorded only in the 2,400–2,600 m range. The five species overlap in the range 2,400–2,600 m, where they occur in three habitats: early regeneration, overgrown alder plantations and 30-year-old forest. There were no differences in density among habitats for any species; the five species used the three habitats in proportion to their occurrence in the landscape. Grallaria milleri had the highest overall density (1.3 ind/ha) while G. squamigera had the lowest density (0.2 ind/ha), and the other three species were intermediate. We estimated 106 individuals of G. milleri in an area of 63 ha, and only seven individuals of G. squamigera. The Otún River watershed concentrates an unusual number of Grallaria antpittas, including three endemic species, and the information presented here is fundamental to any future habitat management plans to ensure the persistence of these populations.
