MINNESOTA’S RING-NECKED DUCK BREEDING PAIR SURVEY David P. Rave, Michael C. Zicus, John R. Fieberg, John H. Giudice, and Robert G. Wright SUMMARY OF FINDINGS A pilot study was conducted in 2004-2006 to develop a survey for Minnesota’s ringnecked duck (Aythya collaris) breeding population because little was known about its distribution and relative abundance. We employed the survey design and methods developed during the pilot study (Zicus et al. 2006) to estimate the size of the population in 2007. The helicopter-based counts (5–13 June 2007) entailed 11 flight days between 2 crews, and included the portion of Minnesota considered primary breeding range. The combined population was estimated to be ~14,500 indicated breeding pairs (~30,300 birds) which is similar to the estimates during the pilot years of the study. INTRODUCTION Staff members in the Minnesota Department of Natural Resources (MNDNR) Wetland Wildlife Populations and Research Group have been developing a forest wetlands and waterfowl initiative. The status of ring-necked ducks has been among the topics considered because the species has been identified as an indicator species for the Forest Province (Minnesota Department of Natural Resources. 2003. A Vision for Wildlife and its Use – Goals and Outcomes 2003 – 2013 (draft). Minnesota Department of Natural Resources, unpublished report, St. Paul). However, little is known about the current distribution and abundance of breeding ring-necked ducks in Minnesota. A 3-year pilot study was used to develop a breeding pair survey (Zicus et al. 2006), and 2007 represented the first year of an operational ring-necked duck breeding pair survey. METHODS 469 Two separate surveys, identical to those used in 2006 (Zicus et al. 2006), were conducted in 2007. We used a stratified random sampling design with 2 stratification variables: (1) Ecological Classification System (ECS) sections; and (2) presumed nesting-cover availability (i.e., a surrogate for predicted breeding ring-necked duck density) to estimate population size in the best ring-necked duck habitat. We used a 2-stage simple random sampling design to estimate population size in the remainder of the survey area. We used a helicopter for the survey because visibility of ring-necked ducks from a fixed-wing airplane is poor in most ringneck breeding habitats. We considered pairs, lone males, and males in flocks of 2 – 5 to indicate breeding pairs (IBP; J. Lawrence, Minnesota Department of Natural Resources, personal communication). The total breeding population in the survey area was considered to be twice the IBP plus the number of birds in mixed sex groups and lone or flocked females. Statistical Population, Sampling Frame, and Sample Allocation The surveys were restricted to an area believed to be primary breeding range of ringnecked ducks for logistical efficiency (Zicus et al. 2005). We used the same habitat class definitions that were used for stratification in the last pilot year (i.e., 2006) (Table 1). Habitat class 1 and 2 plots were presumed to represent the best habitat whereas habitat class 3 and 4 plots represented the remainder of the survey area. Public Land Survey (PLS) sections at the periphery of the survey area that were
