House sparrow whole blood chemistry values in animals fed an oiled diet (1% oil weight:food weight; n = 9) or a control diet (n = 8).

In some cases, blood volume was not sufficient for all analyses, and one animal from the oil group died during week 3 (oiled birds: n = 8 for creatine kinase during week 2, and n = 8 for all analyses during week 4; control birds: n = 7 for aspartate aminotransferase during week 2, and n = 7 for all analyses during week 4). Values were determined using Avian/Reptilian Plus rotors on a portable VetScan machine. Values are presented as mean ± SD (range).
