2. Total number of “hits” at each place.

3. Total number of birds in each area.

4. Without making calculations.

a) would you expect wintering (migrant) birds or resident birds to do better on campus vs the field station? Why?

b) would you expect woodland vs coastal sage species to do better on campus vs the field station? Why?

c) which feeding types would you expect to do best on the campuses, which worst. Why?

Now check the data. Are your predictions correct or not. Why so

5. The original question was, what is the effect of turning the local coastal sage environment into suburbs and campuses.

b) what is the effect on bird species, both in variety and in terms of individual species?

Answer this in terms of feeding types, migrants vs residents, and for individual species.
