Table 1.

The significance of the model parameters for three logistic regressions. The model (A) analyzes how the probability of detecting more than one individual (Y) varies according to the year, the species, and their interaction. The models (B) and (C) analyze how the probability of detecting more than one Zenaida Dove and Bare-eyed Pigeon varies according to the year, respectively.

Model	Parameter	Odds Ratio [95% CI]	X 2	p
(A) Y ~Year + Species + Year × Species	Year	1.183 [1.016; 1.432]	4.742	0.029
	Species	2.148 [1.388; 3.323]	6.817	0.009
	Year × Species	1.219 [1.047; 1.477]	6.801	0.009
(B) Y ~Year (Zenaida aurita)	Year	0.970 [0.935; 1.005]	2.832	0.092
(C) Y ~Year (Patagioenas corensis)	Year	1.442 [1.066; 2.112]	5.821	0.016
