... phospholipids, (2) intramuscular triglyceride stores and (3) adipose tissue triglycerides in free-living white-throated sparrows ( Zonotrichia albicollis ). During migratory seasons there was an increase in the n-6:n-3 ratio of muscle membrane phospholipid fatty acids without a change in the proportion...

... ( Zonotrichia leucophrys ) were studied. The sparrows were divided into two treatments: `winter' (photoperiod 8 h:16 h L:D)and `migrant' (in which migratory condition was induced with a photoperiodic manipulation of 8 h:16 h L:D, followed by 16 h:8 h L:D). Adipose tissue was removed from ruffs and sparrows...
