Kansas 2 0 Shorebird 0 Survey 2 KANSAS FEBRUARY 2003 HELEN HANDS, KANSAS DEPARTMENT OF WILDLIFE & PARKS 2002 KANSAS SHOREBIRD SURVEY PRELIMINARY RESULTS Currently, we have received data for 39 sites (78%) surveyed in During summer-fall, 75,393 shorebirds were reported. spring and 34 sites (68%) surveyed in summer-fall (Fig. 1). Most Shorebird numbers were again highest at CBWA (74%) and volunteers conducted one survey per survey period, 5 in spring QNWR (16%), followed by FNWR (2%) and Fort Riley (2%) and 8 in summer-fall.

Statewide, unidentified shorebirds comprised Cheyenne Bottoms Wildlife Area (CBWA, 73% of statewide 44% of shorebirds recorded; however, most of these were from total), Quivira National Wildlife Area (QNWR, 14%), and The CBWA (Fig. 3).

The peak for the rest of the state occurred during both the last half of April and the first half of May. During summer-fall, statewide shorebird numbers were highest during September (24%), but the peak was much less dramatic than in spring. Shorebird numbers peaked during September at CBWA (Fig. 4). At QNWR, there was no pattern in shorebird numbers. Throughout the rest of the state, shorebird numbers peaked during the last 2 weeks of August and the first 2 weeks of September. These results are very preliminary and it is too early to reach conclusions. Patterns in shorebird migration such as site use, species composition, and timing vary annually in response to many factors, including weather and habitat conditions. Rainfall was below average throughout most of the state before and dur- ing the survey periods. Thus, water levels in most marshes were relatively low and shorebird habitat at such sites was probably FIGURE 2 FIGURE 3 Kansas Shorebird Survey Migration Chronology 2002 80 SPRING LEGEND 70 Cheyenne Bottoms Wildlife Area 60 Quivira National Wildlife Refuge 50 Remainder of State 40 30 Surveys conducted at Cheyenne Bottoms WA, 20 Quivira NWR and 35 sites throughout the rest of the state during 10 spring and summer-fall.

Shorebird spring 2002, 33 sites (70%) surveyed in summer-fall 2002, 33 numbers were again highest at QNWR (38%) and CBWA (34%), surveyed in spring 2003 (68%), and 30 surveyed in summer-fall followed by the Flint Hills National Wildlife Refuge (9%) and 2003 (62%) (Fig. 1). Most volunteers conducted one survey per Marais des Cygnes Area (4%). Because the number of shorebirds survey period, 5 in spring and 8 in summer-fall. However, up to at CBWA and QNWR comprised such a large proportion of 54 surveys were conducted per site.
