OH, those warblers, they make the spring and summer so musical and they make me come over all poetical.
The only transient migrant with sample sizes large enough to estimate tree preferences each year was Yellow-rumped Warbler. Yellow-rumped Warblers were selective in 2011 and 2012 (2011: [x.sup.2] = 19.8, df = 10, P = 0.0064; 2012: [x.sup.2] = 26.8, df = 10, P = 0.0002) but not in 2010 and 2013 (2010: [x.sup.2] = 10.4, df = 10, P = 0.2426; 2013, [x.sup.2] = 7.1, df = 10, P = 0.1229).
