Much of this information resulted from the tireless work of independent researchers and volunteers. However, many of the goshawk studies conducted in the Region should have a caveat attached to the data: All data should be interpreted cautiously. Since many of the cited studies are unpublished, written descriptions of study designs, methods, and analytical techniques are not always available for critical analysis through peer review. No studies have been conducted on a regional scale. Most were conducted in limited portions of one state and, except for Rosenfield et al. (1996), the study locations were not randomly selected which limits the inference value of the data for determining Region-wide trends. There are also problems with small sample sizes, short study duration, and potential bias in nest detection methods. Some of these items have been included rather than excluded with the hope that by sharing as much information as possible, a better understanding of goshawk biology will emerge. It is important to note that no regional inferences should be drawn from these data. A potential outcome of this effort may be an increased awareness of the lack of available information and the need for additional research.enReport
