Bird Survey Programme

 

Survey methodology

1-point counts:

For counting many species of animal in a given area at the same time. to establish which species are present in an area ,and with multiple repetitions of the method, to determine population estimates such as relative abundance and absolute density. For baseline surveys and long-term monitoring.

2- Transects:

For determining the relative abundance and absolute density of numerous species. Very versatile –can be used in many forms on many species types. for baseline surveys and long-term monitoring programs.

3- Quadrates:       

Used for counting species that are relatively stationary. Mostly to determine the relative abundance of different species present in an area, but with multiple repetitions of the method it can also be used to determine the absolute density of species. More suitable for baseline surveys, but also applicable for long-term monitoring .for some species types, it is one of the best methods.

4-capture-mark –recapture:

To aid in determining the population characteristics of various species. Depending on how it is used, it can contribute to estimate of relative abundance and even absolute density. It is used on continental scales to track the migration routes of bird species. It can contribute to long-term monitoring program of specific species.

5- interviews:

To establish the presence or absence of species that are difficult to survey, to get a feel for the abundance of each species in an area, and also to find out where species may most likely be observed.
