连续3年（2016-18年，每年5月至6月）在不同地点利用无线电遥测技术，对中国东南部亚热带极度濒危鸟类蓝冠笑鸫（Garrulax Courtoisi，以下简称BCLT）繁殖期间的栖息地大小和栖息地利用进行了研究。总共对 17 只鸟（12 只雄性、4 只雌性和一只性别未知）进行了标记，并在 54 天的跟踪过程中获得了总共 1515 个位置（平均值 ± 标准误差 = 89.12 ± 11.42）。平均 100% 最小凸多边形 (MCP) 家庭范围大小为 10.05 ± 1.17 公顷，估计的 KDE 核心区域（固定核密度估计器，KDE）大小为 7.84 ± 1.18 公顷。根据 Wilcoxon 秩和检验，男性的 100% MCP 和 KDE 核心面积大小与女性没有显着差异。三个育种地点的 100% MCP 或 KDE 核心面积大小没有显着差异。繁殖地可利用的生境包括水域、灌丛、草地、林地、居民区、菜地、农田、沙滩等；其中，只有林地是 BCLT 显着偏好的。林地（平均使用率为 45.86 ± 1.74%）是 BCLT 强烈首选的筑巢、觅食和栖息地。灌木/草地（24.72±3.39%）和菜地（11.80±1.83%）的使用频率相对高于除林地以外的其他生境，因为灌木通常被用作栖息地，而菜地食物资源丰富。垂直方向上，冠层在4月至6月期间使用最多，但在5月鸟类孵化和育雏时使用最多。这一结果表明 BCLT 在繁殖季节主要活跃在上层。此外，村庄内或村庄附近的阔叶树是鸟类繁殖的重要活动区域；应加强这些地区的保护和管理措施。
The home range size and habitat use of the blue-crowned laughingthrush (Garrulax courtoisi, hereafter BCLT), a critically endangered, subtropical, cooperative-breeding bird species in southeast China, were studied during its breeding period using radio telemetry at different sites during 3 consecutive years (2016–18, from May to June of each year). A total of 17 birds (12 males, four females, and one of unknown sex) were tagged, and a total 1515 locations (mean ± se = 89.12 ± 11.42) were obtained over 54 days of tracking. The average 100% minimum convex polygon (MCP) home range size was 10.05 ± 1.17 ha, and the estimated KDE core area (fiexed kernel density estimator, KDE) size was 7.84 ± 1.18 ha. According to the Wilcoxon rank sum tests, both the 100% MCP and KDE core area size of males did not significantly differ from those of females. There were no significant differences in the 100% MCP or KDE core area sizes of the three breeding sites. The available habitats in the breeding sites included water areas, shrubs, grass plots, woodland, residential areas, vegetable field, farmland, and sandy beaches; among them, only woodland was significantly preferred by BCLTs. Woodland (average use ratio was 45.86 ± 1.74%) was strongly preferred by BCLTs for nesting, foraging and roosting. Shrubs/grass plots (24.72 ± 3.39%) and vegetable plots (11.80 ± 1.83%) were used relatively more often than the other habitats, except woodland, since shrubs were always used as perches, and vegetable plots were rich in food resources. Vertically, the canopy layer was used most often from April to June, but it was used most in May when the birds were hatching and brooding. This result indicates that BCLT is predominantly active in the upper strata during the breeding season. In addition, broadleaved trees within or adjacent to villages were important activity areas for the breeding birds; protection and management measures should be increased in these areas.
