Growing evidence exists tha. a.osema.ic a.d toxic prey ma. be included in a.preda.or＇s diet when the preda.or experiences physiologica. stress. The tree spa.row Pa.ser monta.us is known to ha.e a.significa.t portion of a.osema.ic a.d toxic la.ybirds in its na.ura. diet. Here, we present experi- ments testing the a.ta.k a.d ea.ing ra.e of the tree spa.row towa.d the inva.ive a.osema.ic ha.le- quin la.ybird Ha.monia.a.yridis. We wondered whether the spa.row＇s a.ility to prey on na.ive la.ybirds predisposes them to a.so prey on ha.lequin la.ybirds. We compa.ed the a.ta.k a.d ea.- ing ra.es of tree spa.rows of pa.ticula. a.e a.d/or experience cla.ses to test for a.y cha.ges during ontogeny （ha.d-rea.ed x young wild-ca.ght xa.ult wild-ca.ght） a.d with differing perceived lev- els of physiologica. stress （summer a.ult ~ winter a.ult）. Winter a.ult tree spa.rows commonly a.- ta.ked a.d a.e the offered la.ybirds with no evidence of disgust or meta.olic difficulties a.ter in- gestion. Na.ve a.d wild imma.ure tree spa.rows a.ta.ked the la.ybirds but hesita.ed to ea. them. a.ult tree spa.rows ca.ght in the summer a.oided a.ta.king the la.ybirds. These results suggest tha. tree spa.rows a.e a.le to cope with chemica.s ingested a.ong with the la.ybirds. This pre- a.a.ta.ion ena.les them to include la.ybirds in their diet; though they commonly do this only in times of shorta.e in insect a.a.la.ility （winter）. Young spa.rows showed a.oida.ce towa.d the chemica. protection of the la.ybirds.
