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 3 consecutive years (2016-18, from May to June each year). A total 17 birds (12 males, four females, one unknown sex) tagged, 1515 locations (mean ± se = 89.12 11.42) obtained over 54 days tracking. average 100% minimum convex polygon (MCP) was 10.05 1.17 ha, estimated KDE core area (fiexed kernel density estimator, KDE) 7.84 1.18 ha. According Wilcoxon rank sum tests, both MCP males did not significantly differ those females. There no significant differences or sizes three sites. available habitats included water areas, shrubs, grass plots, woodland, residential vegetable field, farmland, sandy beaches; among them, only woodland preferred by BCLTs. Woodland (average ratio 45.86 1.74%) strongly BCLTs for nesting, foraging roosting. Shrubs/grass plots (24.72 3.39%) (11.80 1.83%) used relatively more often than other habitats, except since shrubs always as perches, rich food resources. Vertically, canopy layer most April June, but it when hatching brooding. This result indicates that BCLT is predominantly active upper strata season. In addition, broadleaved trees within adjacent villages important activity areas birds; protection management measures should be increased these areas.
