Provide supplementary food for songbirds to increase reproductive success
A continuation of (Schoech et al. 2004) between 2000 and 2003 (30), found that breeding groups of Florida scrub jays Aphelocoma coerulescens provided with high-fat, low-protein (HFLP, provided in 2000-2 only) supplementary food started laying eggs significantly earlier than control (unfed) territories, whilst territories provided with high-fat, high-protein (HFHP) food laid significantly earlier still (first laying on average of approximately day 16th March for 50 HFHP territories vs. March 20th for 29 HFLP territories vs. March 28th for 115 controls).
