What is point count data?
The point count survey method is a general sampling approach used to estimate relative abundance and density of bird populations (Ralph, Sauer & Droege 1995; Thompson 2002). This focus on modelling detectability has resulted in a greater application of sampling methods that directly estimate detection probabilities.
What is a disadvantage of the point count method of population?
A disadvantage of the point count method of population monitoring is that it is only beneficial for monitoring organisms, which are fixed in one place. This kind of population monitoring can only be utilized for animals, which attain a fixed position, for example, birds thriving in a specific ecosystem.
What is asbestos PLM?

How do you calculate Bird years?

For example, take the average life expectancy of an American male which is 76, and then divide it by the average age of a budgie which is 9 (76/9 = 8.44).
What is the shortest lifespan of a bird?
