Table 1. A priori hypotheses predicting the relationship between the abundance of different avian guilds and three landscape metrics.

Guild	Hypotheses
	Vegetation	Topography	Standing freshwater
Songbirds [74], [76], [91]	abundance positively correlated with productivity	more abundant in flat vs. rugged habitats	neutral
Shorebirds [92]–[95]	abundance positively correlated with productivity	more abundant in flat vs. rugged habitats	abundance positively correlated with amount of standing water
Gulls [72], [80], [96], [97]	neutral	neutral	abundance positively correlated with amount of standing water
Geese [98]–[100]	abundance positively correlated with productivity	neutral	abundance positively correlated with amount of standing water
Loons [70], [101], [102]	neutral	neutral	abundance positively correlated with amount of standing water
