Males of these species vary in their rates of feeding; Bewick's Wrens feed their incubating mates frequently, whereas House Wrens seldom engage in this behavior. Average length of incubation bout and nest attentiveness (proportion of time spent on the nest) were higher for supplemented female Bewick's Wrens and House Wrens compared to controls. Furthermore, mates of supplemented Bewick's Wrens provisioned females at lower rates than controls, and their rate of feeding was inversely correlated with ambient temperature. Incubation length and hatching success were not significantly different between treatments for either species. These results suggest that incubation mate feeding can increase female nest attentiveness and perhaps enhance fitness of both males and females. In House Wrens, potential tradeoffs between the benefits of parental care and opportunities to obtain additional mates may explain why males rarely feed incubating females.1 aPearse, A.T.1 aCavitt, J.F.1 aCully, J.F.  uhttp://lter.konza.ksu.edu/content/effects-food-supplementation-female-nest-attentiveness-and-incubation-mate-feeding-two01330nas a2200145   4500008004100000245003000041210003000071300001300101490000800114520094700122100001701069700001701086700001701103856006401120       1999                        eng d00aBrown Thrasher Nest Reuse0 aBrown Thrasher Nest Reuse  a859 -8620 v1013 aWe examined the potential functions of old nests in a population of Brown Thrashers (Toxostoma rufum) nesting on the Konza Prairie Research Natural Area in northeastern Kansas. We determined whether thrashers reuse nests constructed in previous years, and tested predictions of the hypothesis that old nests function to reduce the risk of nest predation by saturating the cues used by search-strategy predators. We also manipulated old-nest densities to test the hypothesis that old nests are used as indirect cues for nest-site selection. Thrashers were found to reuse nests, albeit at low rates (4% of nests monitored). We found no significant relationships between the density of old nests and the success of active nests, and experimentally removing nests did not influence nest-site selection. These results suggest that old nests may only benefit thrashers in this population as a resource to reduce the time spent in nest construction.1 aCavitt, J.F.1 aPearse, A.T.1 aMiller, T.A.  uhttp://lter.konza.ksu.edu/content/brown-thrasher-nest-reuse00529nas a2200133   4500008004100000245008300041210006900124300001100193490000700204100001700211700001700228700001800245856013200263       1998                        eng d00aHybridization of Mountain Bluebird and Eastern Bluebird in Northeastern Kansas0 aHybridization of Mountain Bluebird and Eastern Bluebird in North  a21 -320 v491 aCavitt, J.F.1 aPearse, A.T.1 aRintoul, D.A.  uhttps://www.researchgate.net/publication/268287117_Hybridization_o_Mountain_Bluebird_and_Eastern_Blubird_In_Northeastern_Kansas
