A Practical Method to Assess Bird Strike Risk in Air Operations Using a Count‐Based Risk Mitigation Tool

open access: yesRisk Analysis, EarlyView.
ABSTRACT Bird strikes pose a risk to aviation. Collisions between birds and airplanes result in a threat to human lives, economic losses, and material damage. The majority of these collisions occur on airfields during takeoff and landing. Knowing what bird species are present on airfields, in what numbers, and relating that to the extent to which these

Pendulous Crop in Japanese Quail (Coturnix coturnix japonica)

open access: yesPoultry Science, 1974
Abstract Quail chicks from a line selected for growth on a low protein (17.9%) glucose monohydrate-soybean meal diet showed a high incidence, 44.0%, of pendulous crop as compared to 11.8% in the control line fed the same ration. Substituting sucrose for glucose monohydrate did not change the incidence of pendulous crop in either the control or the ...

Are biologically meaningful effect sizes a factor in study design? A systematic review of translational chronic variable stress studies

open access: yesExperimental Physiology, EarlyView.
Abstract The design of in vivo studies using laboratory animals is normally guided by the 3Rs: Replacement, Reduction and Refinement. The concept of Reduction is particularly important in the context of estimating sample size; the selected sample size should allow the detection of a predetermined effect size using appropriate statistical tests, but not

Saltatory axonal conduction in the avian retina

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Intraretinal axonal spike conduction was studied across multiple avian and mammalian species using high‐resolution multielectrode arrays. On the electrode array, saltatory axonal spike conduction was readily apparent and distinguishable from non‐saltatory conduction.

Determining population trends and conservation status of the common quail (Coturnix coturnix) in Western Europe [PDF]

open access: yes, 2012
In this paper we review the conservation status and population trends of the common quail (Coturnix coturnix) from 1900 to the present. Data are sometimes contradictory with regard to the status of this species as it has some features that make it ...

Efeito dos níveis de triptofano digestível em dietas para codornas japonesas em postura Dietary digestible tryptophan levels for Japanese laying quails

open access: yesRevista Brasileira de Zootecnia, 2008
O nível dietético adequado (0,12; 0,16; 0,20; 0,24 e 0,28%) de triptofano digestível foi avaliado em 400 codornas japonesas de 21 a 30 semanas de idade, fase de postura. As codornas foram alojadas em gaiolas de 125 cm²/ave, com peso inicial de 158,50 g e

Crude protein in diets for European quail (Coturnix coturnix)

open access: yesSemina: Ciências Agrárias, 2020
The aim of this study was to evaluate the influence of dietary crude protein (CP) levels on the production performance, carcass traits and dietary nutrient metabolizability of European quail from one to 35 days of age. A total of 250 quail were allotted to one of five treatments (21, 22, 23, 24 and 25% CP) in a completely randomized experimental design

Cantharidin world on bird droppings: Reused cantharidin after bird predation of cantharidin‐producing insects

open access: yesEntomological Science, Volume 28, Issue 4, December 2025.
Cantharidin is produced only by beetles of Meloidae and Oedemeridae families and is a rare resource for canthariphilous insects that ingest fluids and/or portions of living and even dead meloid and oedemerid beetles. This study reports that the canthariphilous insects also use cantharidin that remains in bird droppings produced after eating meloid or ...
