The record of the latest active nest in the orchard is August 31st. With the advent of the hunting season or the first cold, -early fall weather there is a general emigration from the study area. Between the hunting loss and the effect of this dispersal very few dove remain about the area by the end of September. THE FOOD HABITS Collection During the course of the study 275 dove crops were collected for analysis. They were collected on a monthly basis from the time the birds first arrived on the area until they dispersed with the advent of the September hunting season. Ninety-nine of the crops were taken from hunter-killed birds and the contents of 70 were obtained by flush- ing the crops of nestling birds with water. The remainder were collected at random in the study area by shooting. The method used to sample the food habits of the nestling birds has been described by Macgregor (1958). This technique consists of flood- ing the crop with water and flushing the contents into a piece of cheese- cloth (Figure 4). ijf: f 4. FIGURE 4.
