Molecular identification and phylogenetic analysis of the mitogenome in endangered giant nuthatch (, ).

The Giant Nuthatch (family Sittidae) is a passerine bird, the quantification of the number of habitats and species on a global scale remains low. Most species are restricted to low elevations in southwest China, eastern Myanmar, and northern Thailand. To characterize the mitochondrial genome sequence of and its phylogenetic relationships with other members within the genus , the mitochondrial genome of was sequenced using the whole genome shotgun method.

Nest-Site Features and Breeding Ecology of Chestnut-Vented Nuthatch in Southwestern China.

The breeding ecology of birds is the cornerstone of bird life-history theory, and breeding success directly affects the survival and development of populations. We studied the breeding ecology of a secondary cavity-nesting bird, the chestnut-vented nuthatch , in southwestern China from March to June in 2020, 2021, and 2022. In total, 16 nests in nest boxes and 19 nests in natural cavities were studied.
