Case 1 High density population 
Assumptions: 1. Single species 
2. All nests have the same r 
3. Unrestricted nest sites 
Predictions: 1. Overdispersed nest array 
2. Nest to nest distance ~ 2 r 
Case 2 Low density population 
Assumptions: 1, 2, 3 
Predictions: 1. Nest distribution will tend to randomness 
2. Average nest to nest distance >2 r 
3. High variance in nest to nest distance 
Case 3 Limited nest sites 
a. Assumptions: 
Predictions: 
b. Assumptions: 
Predictions: 
1 , 2 
1. Nests more overdispersed than potential nest sites 
2. Nest spacing will vary with nest site location, minimum nest 
to nest distance = 2 r, average nest to nest 
distance >2 r 
3. High variance in nest to nest distance 
1 
1. Nests distributed as nest sites 
2. Asymmetric foraging ranges 
Case 4 Intraspecific = interspecific interactions 
Assumptions: 2, 3 
Predictions: 1. Entire nest array overdispersed 
2. Individual species are more randomly dispersed than the 
total array 
3. No pattern in the identity of nearest neighbor 
4. High variance in nest to nest distances within a species, 
average nest to nest distance >2 r 
5. Low variance in nest to nest distances for the entire array, 
average nest to nest distance = 2 r 
Case 5 Intraspecific interactions > interspecific interactions 
Assumptions: 2, 3 
Predictions: 1. Entire nest array overdispersed 
2. Individual species within the array are also overdispersed 
3. Nearest neighbors tend to be members of other species 
4. Low variance in nest to nest distances within species, average 
nest to nest distance >2 r 
5. Low variance in internest distances for the entire array, 
average nest to nest distance = 2 r
