The Survey of Density and Diversity of Birds in Two Protected and Recreational Forest Areas (A Case Study: Golestan Province, Iran)
Density and diversity of birds in two different forest zones, namely, Shasta Kalateh Protected Forest and Alangdareh Recreational Forest, were estimated and compared. Birds and environmental variables were recorded within 25 m radius in 100 sampling points. The first axis of Canonical Component Analysis segregated two main groups of birds. The first group consisted of Black Woodpecker, Great Sp...

متن کاملA review of flight-initiation distances and their application to managing disturbance to Australian birds
Disturbance – the response of birds to a stimulus such as the presence of a person – is considered a conservation threat for some Australian birds. The distance at which a bird flees from perceived danger is defined as the flight-initiation distance (FID), and could be used to designate separation distances between birds and stimuli that might cause disturbance. We review theknownFIDs forAustra...
متن کاملHuman Disturbance during Early Life Impairs Nestling Growth in Birds Inhabiting a Nature Recreation Area
Nature recreation conflicts with conservation, but its impacts on wildlife are not fully understood. Where recreation is not regulated, visitors to natural areas may gather in large numbers on weekends and holidays. This may increase variance in fitness in wild populations, if individuals whose critical life cycle stages coincide with periods of high human disturbance are at a disadvantage. We ...
متن کاملHeart rate responses provide an objective evaluation of human disturbance stimuli in breeding birds
Intuition is a poor guide for evaluating the effects of human disturbance on wildlife. Using the endangered Yellow-eyed penguin, Megadyptes antipodes, as an example, we show that heart rate responses provide an objective tool to evaluate human disturbance stimuli and encourage the wider use of this simple and low-impact approach. Yellow-eyed penguins are a flagship species for New Zealand's wil...
