Table 1 Mean (± SD) per transect for estimators of food resource availability for Military Macaws in tropical deciduous and semi-deciduous forest at two sites along the coast of Jalisco in the dry season

From: Optimal diet strategy of a large-bodied psittacine: food resource abundance and nutritional content enable facultative dietary specialization by the Military Macaw

Variable Deciduous Semi-deciduous Significance value
Tree species fruiting 5.7 ± 1.7 5.5 ± 2.2 t15 = 0.17, ns
Number of fruiting trees 9.3 ± 5.2 14.3 ± 6.8 t15 = 1.65, ns
Sum of DBH of fruiting trees 259.3 ± 197.5 444.3 ± 136.3 t15 = 2.26, p < 0.03
Sum of fruit abundance ranking 16.3 ± 6.4 20.0 ± 20.5 t15 = 0.49, ns
  1. Two-sample t test significance values are shown. No resources were recorded in pine-oak forest, therefore this habitat was excluded from analysis
