The mite fauna inhabiting nests of various birds in Bulgaria and the world as a whole not yet been insufficient studied. Data of mites of many species of birds, one of which is Ficedula semitorquata are still scarce. The aim of the present paper is to describe the taxonomic diversity and distribution of astigmatic, prostigmatic and mesostigmatic mites in nests of semi-collared flycatcher in North-East Bulgaria. Differences in the species richness and abundance of mites at studied nest-box plots were assessed using Analysis of Variance (ANOVA). Pairwise comparisons were performed using Tukey´s tests. Twelve species, belonging to seven families of mites (Dermanyssidae, Macronyssidae, Laelapidae, Myonyssidae, Macrochelidae, Cheyletidae and Acaridae) were recorded. 157 (83.51%) of investigating 188 nests were infested with mites and the average abundance per nest was 21.24. The distribution of the found species in the nests and nest-box plots is uneven.

Majority of Anna's hummingbirds may have feather mites on their tail feathers

Hummingbirds are known to host a diversity of feather mites, but this relationship is not well-understood. In particular, mite distribution in situ has not been previously studied. The authors of the present study examined 753 hummingbirds of five species from urban locations in California: Anna's, Allen's, Black-chinned, Calliope and Rufous Hummingbirds. They documented the presence of the feather mite Proctophyllodes huitzilopochtlii on tail flight feathers.

The researchers found that feather mites were present on the tail flight feathers of nearly 60 percent of Anna's hummingbirds, but less than 10 percent of the other species. Across all the species, the mite was more prevalent on the tail feathers of males (44.9 percent) than on those of females (36.2 percent), possibly because of the nesting habits of females.

The authors used tabletop scanning electron microscopy to analyze individual feathers, building a detailed 3D picture of the distribution of live mites in situ. They found that there tended to be more mites on the hummingbirds' outer tail feathers than inner, and saw that mites often nestled between the barbs of individual feathers, sometimes in high numbers.

The authors state that their study provides the first prevalence and distribution information for these feather mites on both Anna's and Black-chinned Hummingbirds. This is especially important given that Anna's Hummingbirds co-reside seasonally with other hummingbird species, with the potential for spread of mites.
