  1. Protect nests from ants

    A randomised, replicated and controlled study in March-July 2006-7 in a grassland/oak-juniper woodland mosaic in Texas, USA (Campomizzi et al. 2009) found that 18 white-eyed vireo Vireo griseus nests, protected from red imported fire ants Solenopsis invicta with a physical barrier and a chemical repellent, had significantly higher fledging success than 26 unprotected nests (31% vs. 10%). The same effect was seen in 13 experimental and 14 control black-capped vireo V. atricapilla nests, but this difference (13% vs. 7%) was non-significant. The physical barrier was Tanglefoot – a gum resin that traps crawling insects, applied to the branch >25 cm from each nest; the repellent was Arinix™ spiral wrap – a permethrin releasing plastic wrapped around the branch on top of the Tanglefoot.
