Mechanisms of food size selection by bullfinches (Pyrrhula pyrrhula L.) feeding on sunflower seeds
Abstract Size-selective feeding is usually discussed in relation to ‘optimal diet’ models, which provide no indications of mechanisms of choice. In a series of experiments, captive bullfinches wereExpand
Repellency of cinnamic acid derivatives to rooks and chaffinches
AGUERO, D. A., R. J. JOHNSON, K. M. ESKRIDGE, J. E. KNIGHT, AND D. H. STEINEGGER. 1989. Monofilament lines repel house sparrows. Proc. Great Plains Wildl. Damage Control Workshop 9:181. , AND . 1991.Expand
Risk Assessment of UK Skylark Populations Using Life-History and Individual-Based Landscape Models
Following a workshop exercise, two models, an individual-based landscape model (IBLM) and a non-spatial life-history model were used to assess the impact of a fictitious insecticide on populations ofExpand
Estimating the Exposure of Birds and Mammals to Pesticides in Long-term Risk Assessments
This paper reviews current EU pesticide risk assessment guidance [European Commission (2002) Guidance document on risk assessment for birds and mammals under council directive 91/414/EEC,Expand
Repellency of cinnamic acid derivatives to captive rock doves
Many plant secondary compounds are known to deter feeding in herbivores and could provide a fruitful source of chemical repellents. Consequently, we tested a range of cinnamic acid derivatives forExpand
Plant chemistry and bird repellents
Research into chemical bird repellents is reviewed. The feeding preferences of Bullfinches Pyrrhula pyrrhula for bud extracts of 26 pear cultivars were established in the laboratory and correlatedExpand
Repellency and choice: feeding responses of wild rats (Rattus norvegicus) to cinnamic acid derivatives
Abstract Plant secondary compounds and other chemical compounds known to deter feeding in birds were tested for their repellency against wild rats under two-choice and no-choice conditions. InExpand
Case Study Part 2: Probabilistic Modelling of Long-term Effects of Pesticides on Individual Breeding Success in Birds and Mammals
Long term exposure of skylarks to a fictitious insecticide and of wood mice to a fictitious fungicide were modelled probabilistically in a Monte Carlo simulation. Within the same simulation theExpand
Case Study Part 1: How to Calculate Appropriate Deterministic Long-Term Toxicity to Exposure Ratios (TERs) for Birds and Mammals
In the European Union, first-tier assessment of the long-term risk to birds and mammals from pesticides is based on calculation of a deterministic long-term toxicity/exposure ratio (TERlt). The ratioExpand
Estimating the potential effects of pesticide seed treatments on the reproductive success of arable birds.
In temperate zones, seeds of spring-sown crops may be an attractive food source for breeding farmland birds. We modelled the effects of pesticide seed treatments on the reproductive success of 4 UKExpand
