My class presentation for Fall 2012's FS111 class, Behaviour & Ecology of Bats, at Northern Arizona University, taught by Carol Chambers, PHD. Carol Chambers, PHD noted that this was easily the most visually impressive and well-thought out PowerPoint presentations she had seen in her career. I received a 100/100 on the assignment and a A in the class.

1. The Lesser Long-Nosed Bat
A presentation
by Joel Fenton

2. The Lesser Long-Nosed Bat
Scientific name: Leptonycteris yerbabuenae
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Chiroptera
Family: Phyllostomidae
Genus: Leptonycteris
Species: L. yerbabuenae

3. Also commonly known as…
•Sanborn's long-nosed bat
•Mexican long-nosed bat
Names are derived from the bats appearance…

4. Appearance:
•Long, leaf shaped nose
•Pelage color ranging from
yellow-brown to gray
•Rusty coloring on stomach
•No visible tail, small ears
•Long tongue used for
feeding
•Small in size, 0.4 to 0.7
ounces
•Adult wingspan of 14 inches

5. Habitat
The Lesser
Long-nosed bat
commonly lives
in abandoned
mines, caves,
caverns, and
rock crevices in
desert
scrubland
habitat.

6. Home
“Thousands of these bats
will spend their day roosting
in caves or mines. Caves and
mines offer general safety
from predators, provide the
proper temperature, are
used as maternity sites, and
places to rest during
migration” (Arizona-Sonoran
Desert Museum).

7. Range
Lesser Long-nosed
bats are found in
southern Arizona and
southwestern New
Mexico, western
Mexico, Baja
California del Sur and
into Central America.

8. Diet
The Lesser Long-nosed bat
feeds on nectar from
flowers, fruit, and humming
bird feeders.
They love the
nectar that
comes from
saguaro and
organ pipe, as
well as many
species of
agave.

10. Fun Facts
•Lesser Long-nosed Bats can reach speeds of 14 miles per hour
•Lesser Long-nosed Bats can live up to 20 years
•These bats are nocturnal in order to feed from plants like saguaro
cactus whose flowers open at night.
•These bats have a long slender face as well as a long tongue which
enables then to better reach inside the flower for the nectar.

11. Lesser long-nosed bats roost during the day in large colonies of up to
several thousand individuals in caves or abandoned mines, dispersing at
night to feed.
At some times of the year, many colonies become occupied only by
nursing females and their young, with males occupying smaller temporary
roosts
Communal?

12. Reproduction
The breeding season lasts from November to
December for bats that migrate northward during
the summer, but from May to June in those that
give birth in the south. Despite the presence of
two distinct mating seasons, individual bats mate
only once a year. Gestation lasts about six
months, and results in the birth of a single pup,
during the time of local peak flower availability.
Newborn young weigh 4 to 7 grams (0.14 to 0.25
oz) and are fully weaned at four to eight weeks of
age. They are able fly after a month, but do not
begin to exit the maternity cave for a further two
to three weeks. They are known to live for up to
at least eight years in the wild.

13. They are able to tolerate unusually high temperatures of
up to 41 °C (106 °F), due in part to a low metabolic rate.
They do not enter torpor or hibernate, but die at
ambient temperatures of below about 10 °C(50 °F).
In the north, they reach southern California, Arizona and New Mexico.
However, they are only found as summer migrants in the United
States and, more generally, north of the mid-Sonora, arriving in these
regions between April and July, and migrating south again in September.
Some individuals have been estimated to migrate as far as 1,600
kilometers (990 mi) each year. They are found year round in the western
and southern parts of Mexico, and long the east coast, and
in Guatemala, El Salvador, and Honduras
Temperature Tolerance and Migration

14. Predators
Predators such as owls, snakes and bobcats will wait at
cave entrances or interiors looking for individual bats
who have fallen to the ground or those that they can
catch in flight.

15. Conservation Status
This species of bat is considered
vulnerable to extinction, but is not
considered in serious immediate danger.
