Exam 3 Flashcards
What is a point count?
Is it an active or passive survey method? What does this mean?
What is the typical duration of a point count?
What might determine the duration that is needed?
What detection cues are used during a point count?
What kind of bias can be introduced because of this?
What is the first thing to do when you get to your point count location?
What is metadata and what kinds are involved in point counts?
Under what conditions should you not do point counts, and why?
What time of day (be precise) is best for point counts?
Why?
What time of year is best for point counts?
Why?
What data should you record for each observed bird during a point count?
Describe the differences between fixed radius and unlimited radius point counts.
Describe proper point count location placement with regards to edge and neighboring points, and why each is appropriate.
Define detection probability.
What factors affect it?
How are repeated surveys related to detection failure?
What assumption is critical for this to work?
How are repeat surveys timed in relation to one another? Can they be done at the same time?
What is the difference between occupancy and abundance?
What types of species might each be appropriate for?
What is distance estimation in point counts? How is it used?
Describe in general how to keep track of individual birds during a point count so they are not double counted.
What are the 6 assumptions made for point counts?
What gear is needed for a point count?
What are 6 pros of point counts?
What are 6 cons of point counts?
How do we overcome the coarseness of point counts? Why is this helpful?
What is species richness?
How does it compare to diversity?
Besides habitat related factors, what is another big factor that affects detection probability? What are some examples?
Describe the Beaufort Wind Index in detail. What kind of measurement is this?
How is cloud cover described for a point count? What kind of data is this and how can it be analyzed?
What kind of relationship does temperature have with detection probability? What does this mean?
How is time of day described/expressed during analysis?
What type of relationship(s) does it have to detection probability?
How is the date described/expressed during analysis?
How does it relate to detection probability? Why?
What is playback? When should it not be used?
Does playback improve detection probability? Why?
