Hello my lovely friends I am again here on steemit platform with a new post my this post will be about Hummingbird so my dear friends I will show you interesting information about Hummingbird so let's see.
Adult female Ruby-throated Hummingbirds (RTHU) are 15-20% Larger than adult males MASS: About 3-4g (a nickel weighs about 5g); may nearly double mass prior to migration by putting on extra fat.
LENGTH: About 8.5cm (3.5") from tip
of bill to tip of tail
FLEDGLING SIZE: Hummingbirds are
full-grown when they leave the nest,
baby hummingbirds cannot fly
WING BEATS: About 60-80 times per
second in normal flight, up to 200
times per second in courtship dives
SPEED: Normal flight about 25mph; up
to 65kph (40mph) in a courtship dive
FLIGHT MUSCLES: Make up about
25% of RTHU's weight (compared to
5% pectoral muscle weight in human
beings)
HEARTBEATS: About 250 times per
minute while at rest, about 1,220 per
minute while flying
HEART SIZE: About 2.5% of total body
weight
NEST SIZE: Inner diameter of about
4cm (1.5"), the outside of the nest is
about 6cm (2.25") tall.
EGG SIZE: 8mm x 13mm (25" x .5"),
roughly the size of a small jellybean
EGG COLOUR: White, non-glossy
Most hummingbirds die within their
first year, those that don't probably
live an average of 3 years or so
Chicks are naked and about 2.5cm
(1") long at hatching. Mass is doubled
each day over the first several days.
BODY TEMPERATURE: 40.5 degrees C
(105-108 degrees F)
A typical RTHU has 940 feathers
NEST MAKEUP: Spun by the female
from spiderwebs and plant material,
camouflaged with bits of lichen, lined
with plant down
NEST LOCATION: Eastern United
States and southern Canada in mixed
woodlands, orchards, suburban areas
with shade trees, etc.; often on an
edge" between open area and woods
NEST SITE: 2-18m (6-50) above
ground, usually attached to a small,
downward-sloping twig and often near
water, nest site-but not the nest-may
be used from year to year
NESTLINGS: NUMBER OF EGGS PER
NEST: 2, sometimes 1, almost never 3
INCUBATION: About 16-18 days
(perhaps longer in cool weather), by
female only.
FEEDING OF YOUNG: Female collects
nectar and tiny insects in her crop,
then regurgitates the slurry into
mouths of nestlings
AVERAGE AGE: RECORD AGE: The
oldest known RTHU is listed at about
9 years.
