This article in Earth.com summarizes a study published in Biology Letters. Scientists from Penn State and ABC studied 13 spp over 20 years and compared Robert MacArthur's study of niche partition of tree foliage and feeding behavior, completed ~70 yrs ago. The new study includes genetic analysis of insect diets which were very similar among bird spp ---which might be expected. There is a link to the original publn in Bio Letters, if you can open it.
