Black-Chinned Hummingbird vs Calliope Hummingbird
A black-chinned hummingbird and a calliope hummingbird are both small western hummingbirds that migrate impressive distances each year, yet each is defined by a completely different standout trait, one hidden in its throat colour and the other in its sheer size.

Black-Chinned Hummingbird vs Calliope Hummingbird: common questions
Which of these two hummingbirds is smaller?
The calliope hummingbird is smaller, in fact the smallest breeding bird species found anywhere in North America, while the black-chinned hummingbird, though still a small bird by any ordinary standard, is noticeably larger by comparison.
Why doesn't the black-chinned hummingbird's throat always look purple?
A male black-chinned hummingbird's throat appears mostly plain black under most lighting because the thin band of iridescent purple along its lower edge only becomes visible when light strikes the feathers at a very specific angle, unlike the calliope hummingbird's streaked magenta throat, which reads as colourful from a wider range of viewing angles.
Which of these hummingbirds breeds at higher elevation?
The calliope hummingbird breeds at notably high mountain elevations, tolerating cooler conditions than many hummingbird relatives, while the black-chinned hummingbird occupies a broader range of elevations, from desert canyons up through forest edges, without being tied to such consistently high mountain terrain.
