Live blind snakes (Leptotyphlops dulcis) in eastern screech owl (Otus asio) nests: a novel commensalism

  title={Live blind snakes (Leptotyphlops dulcis) in eastern screech owl (Otus asio) nests: a novel commensalism},
  author={Frederick R. Gehlbach and Robert S. Baldridge},
SummaryEastern screech owls bring live blind snakes to their nestlings, whereas all other prey are delivered dead. Some of the snakes are eaten but most live in nest debris, where they eat soft-bodied insect larvae from the decomposer community in fecal matter, pellets, and uneaten prey. Consumption of larvae may reduce larval parasitism on owl nestlings or larval competition with nestlings for food stored in the nest, because nestlings with live-in blind snakes grow faster and experience lower… Expand
A Case of Protocooperation between the Pitviper Gloydius ussuriensis and the Ground Beetle Carabus granulatus telluris
The present publication describes a previously unknown case of this form of symbiosis between a snake and an insect, namely between the pitviper Gloydius ussuriensis Emelianov, 1929 and the ground beetle Carabus granulatus telluris Bates, 1883. Expand
Eggs of the Blind Snake, Liotyphlops albirostris, Are Incubated in a Nest of the Lower Fungus-Growing Ant, Apterostigma cf. goniodes
Other associations between nesting fungus-growing ants and egg-laying vertebrates are reviewed, which suggest that attine nests may provide a safe, environmentally buffered location for oviposition, even in basal attine taxa with relatively small colony sizes. Expand
Life cycle of Anthracophora rusticola (Coleoptera: Cetoniidae) from the commensal nests of Chinese Sparrowhawks (Accipiter soloensis)
Examining the breeding cycle of the declining A. rusticola related to that of nesting Chinese sparrowhawks in Korea and the coinciding breeding of two commensal taxa over three months from May to September may provide key information regarding the life history and potential causes of the concurrent decline of both taxa.

How Birds Combat Ectoparasites
The evidence - or lack thereof - for many of the purported mechanisms birds have for dealing with ectoparasites are reviewed, focusing on features of the plumage and its components, as well as anti-parasite behaviors. Expand
Some observations on the nesting behaviour and food of the Spotted Owlet Athene brama
1163 Abstract Observations on the nesting behaviour and food of the Spotted Owlet Athene brama occupying a wooden nest box were recorded in March-April 2002 at Anand, Gujarat. The clutch size wasExpand
Do House Wrens (Troglodytes aedon) add spider egg cases to their nests for heterospecific cleaning
House Wrens regularly add spider egg cases (Arachnida: Araneae) to their nests, which may be an example of heterospecific cleaning. Expand
Ectoparasitism as a possible cost of social life: a comparative analysis using Australian passerines (Passeriformes)
The hypothesis that cooperative breeding entails a cost in terms of transmission of ectoparasites was tested by a comparative analysis among sympatric Australian passerines. The general trend foundExpand
Immunocompetence and Parasitism in Nestlings from Wild Populations
It is suggested that parasite-induced nestling mortality in birds is mainly determined by geographical location and to a smaller extent nest site and parasite prevalence and the naive immune system of nestlings and the difficulties to avoid infection once the nest has been located imply a high potential impact of parasites on nestlings.

Morphology of the lower jaw and suspensorium in the Texas blindsnake, Leptotyphlops dulcis (Scolecophidia: Leptotyphlopidae)

  • Biology, Medicine
  • Journal of morphology
  • 2006
Several anatomical features of the jaw apparatus suggest that Leptotyphlops evolved from more typical snake‐like ancestors that had already lost the firm symphysis between the distal tips of the mandibular rami; and had already evolved a high degree of upper jaw mobility. Expand
The threadsnake tangle: lack of genetic divergence in Epictia tenella (Squamata, Leptotyphlopidae): evidence for introductions or recent rafting to the West Indies
Hypotheses that may explain the low divergence for this small, fossorial snake are explored and discussed: over-water rafting, human-mediated dispersal, and avian- mediated dispersal. Expand


Comparative Analysis of the Feeding Habits of Two Species of Arizona Blind Snakes, Leptotyphlops h. humilis and Leptotyphlops d. dulcis
The purpose of the present study was to accurately analyze the feeding habits of these two species in an area of sympatry as well as to determine what differences, if any, exist in their food preferences. Expand
Attractant‐Repellent Secretions of Blind Snakes (Leptotyphlops Dulcis) and Their Army Ant Prey (Neiv Amyrmex Nigrescens)
For blind snakes, theRepulsion of their predators and competitors may be more important than repulsion of ants, and the function of intraspecific attraction is viewed as most important in this complex system of chemical regulation. Expand
Raptor nests as a habitat for invertebrates: a review
Invertebrates in raptor nests may be classified into three maior groups: parasite fauna, animal saprovores, and humus fauna. The parasite fauna includes raptor and prey parasites and theirExpand
Invertebrate Use of Natural Tree Cavities and Vertebrate Nest Boxes
It is important that invertebrate use of artificial and natural cavities be quantified so habitat loss by cutting of cavity-bearing trees, as well as the benefits of box erection, can be assessed on the basis of all terrestrial fauna, and not just vertebrates, as is so frequently the case. Expand
Microclimates of Nest Boxes and Natural Cavities in Bottomland Hardwoods
The ecology of wood duck (Aix sponsa) in the Piedmont region of South Carolina and nest boxes as nest sites for Australian waterfowl are studied. Expand
