The mute swan is a species of swan and a member of the family Anatidae within the waterfowl order. It is native to much of Europe and parts of Asia and the far north of Africa. It is an introduced species in North America, home to the largest populations outside of its native range, with additional smaller introductions in Australasia and Southern Africa. The name "mute" derives from it being less vocal than other swan species. Typically measuring 140 to 160 cm in length, this large swan is wholly white in plumage, with an orange beak bordered with black. It is recognisable by its pronounced knob atop the beak, which is larger in males.
Male-like ornamentation in female hummingbirds results from social harassment rather than sexual selection
Female white-necked jacobin hummingbirds are polymorphic—some express ornamented plumage like adult males. Falk et al. find that all juvenile females have male-like plumage, which some maintain as adults. Rather than being favored by sexual selection, male-like plumage benefits females by reducing social harassment from this and other species.

The sound of the trees
Early in the morning, before dawn has even fully broken over Berlin, a concert of a very special kind begins under Susie Ibarra’s window. The blackbird begins with a short melodic solo ending on a trill, its song accompanied by the rustling of the horse chestnut leaves on the branches outside Ibarra’s window. For the artist, this is much more than just an acoustic welcome to the day – it is a dialogue with nature and a chance to immerse herself in a musical realm full of rhythms and sounds.

Where the Birds Sing Bass — Lockett, Reginald — Poetry. "WHERE THE BIRDS SING BASS may be the best book of poetry in 1995. The voice is hip, urban, observant, and nostalgic. Reginald Lockett brings the world home, and in the process tells us about folks who don't make the news" -Ishmael Reed.
