component of the project by this coming fall.<br />

In addition, I have conducted preliminary analyses to<br />

look at the relationship between weather <strong>and</strong> annual<br />

recruitment. These indicate a strong role for summer<br />

conditions in predicting reproductive output (Fig. 2).<br />

However, these were based on a relatively short<br />

sampling period (3 years) <strong>and</strong> ignored spatial issues.<br />

Once wing data <strong>and</strong> weather covariates are available<br />

for 2012, I will begin to integrate this component<br />

into the estimated recruitment model.<br />

Figure 2. Preliminary results suggest summer conditions<br />

can affect mourning dove recruitment at the regional<br />

level. This figure shows the relationship between<br />

residuals for the annual proportion of hatch year wings in<br />

the mail survey sample <strong>and</strong> the residual for the annual dry<br />

heat index for 2007 to 2009. Each point represents values<br />

for a single year <strong>and</strong> region combination (regions were<br />

southeast, south-central, southwest, northeast, northcentral,<br />

<strong>and</strong> northwest). Future work to explore these<br />

patterns will incorporate additional years of data <strong>and</strong> a<br />

more robust methodology to estimate effects<br />
