In all other years, nesting <br />information was obtained between 21 April and 6 May. <br />SANDHILL CRANE ACTIVITY <br />Although sandhill cranes were documented within the permit area in late April 2007, no <br />nesting activity was observed during the site visit. Biologists recorded one adult sandhill crane <br />foraging within reclamation in SE SW Section 12, TSN, R87E on 22 April. Cranes nested <br />nearby, from 2004 through 2006, at the periphery of a mine reservoir at the south edge of the <br />permit area in SW SE Section 12. When biologists checked that site for activity on 22 April, <br />what could have been the foundation of a potential nest (a small hummock of cattail [Typha <br />-• spp.]) was observed in the same general location as previous years' nests. However, the high <br />water level at the site had flooded the cattail stands sufficiently as to discourage nesting at that <br />time. Despite searching other potential nesting sites, no nests or other cranes were observed on <br />or near the Seneca II permit area in 2007. <br />• <br />LITERATURE CITED <br />Cannon, R.W. and F.L.
