I had the opportunity to photograph the Ruby-throated Hummingbird enjoying Royal Catchfly (Silene regia). I am assuming this is a female. This fascinating species favor red tubular flowers most of all. Royal Catchfly, a native of Missouri, is an excellent candidate here. Photographs taken on July 20, 2014 in Waukesha County, Wisconsin.
Binomial name: Archilochus colubris
Description: Metallic green feathers on back, grayish-white on underparts. Males have a vibrant red throat which may appear dark in poor lighting. Wings are dark gray, almost black. Long, slender bill is black in color and mostly straight with a slight curve at the tip.
Size: 2.8″-3.5″ long, 3” – 4” wingspan
Weight: 0.071 oz. – 0.21 oz.
Habitat: Broadleaf and pine forests, orchards, meadows, parks, and gardens
Diet: Tree and flower nectar, small insects, and spiders
Nesting: The female provides all parental care, building a nest in a protected tree or shrub on a slightly downward-sloping limb. They favor deciduous trees such as oak, birch, or poplar. The nest is made out of bud scales, lichen, spider silk, and dandelion or thistle down. The same nest may be used year after year with the female making annual repairs. The female will lay 1-3 eggs at a time, laying eggs once or twice per summer. The young remain in the nest for 22-25 days.
