Editing Blue-gray gnatcatcher (section)

==Diet and behaviour==
Blue-gray gnatcatchers prefer humid areas with large leaves, [[Woodland|woodlands]], and more open sandy areas with sparse trees where they mainly eat [[Insect|insects]], [[Insect egg|insect eggs]], and [[spider]]s. The males often work to build nests, help [[Egg incubation|incubate]] and raise the young, as well as feed the children, often thought to be a mother's role. Their nests are often built far out on a tree's branch with spider silks and [[lichen]] plants holding them together.<ref>{{cite journal |last1=González-García |first1=Fernando |title=First record of non-migratory Blue-gray Gnatcatcher (Polioptila caerulea) as a host to the Bronzed Cowbird (Molothrus aeneus) in Mexico |journal=The Wilson Journal of Ornithology |date=2020 |volume=132 |issue=3 |doi=10.1676/20-96 |s2cid=233429970 |url=https://doi.org/10.1676/20-96|url-access=subscription }}</ref> They may hover over foliage while snatching prey ([[gleaning (birds)|gleaning]]), or fly to catch insects in flight ([[hawking (birds)|hawking]]).
