108 the study area it was impossible within the limits of time and money to completely cover the area of interest on each flight. When possible, flying storks were followed to feeding areas to locate feeding congregations. On weekend or 1-day flying sessions, however, it proved more profitable to make searching flights over areas where water levels suggested Wood Storks might be feeding. As the season progressed, these areas became more limited. Water levels in various sections of the study area were spot- checked by air periodically. Feeding areas also were located by identifying the major flight line of Wood Storks into and out of the rookery area on a given day and concentrating the search along that radial. Observations during the aerial survey led to the estimate of the total land area in southwest Florida currently supporting wading birds and the number of birds supported per unit area. From these estimates, calculations were made of the number of birds per hectare and the gram weight of birds per hectare. Characteristics of the Wood Stork Population Hypothetical Life Table The limited information on Wood Stork demography, supplimented by estimates based on the demography of related species, formed the background for a life table of the Wood Stork to provide information for use in Model Ill.
