Mostly about my backyard chickens. (Boring, I know), but there are a lot of us out here. Mine are only kept as pampered pets. I could eat a neighbor's chicken, but not MINE. There may be a comment on current events only if I get riled up enough. And there will always be a cartoon or a joke to cheer us. I promise to try my very best to respond to comments. Now I have to figure out how this blogger thingy works....
African Bullfrogs, also known as Giant Bullfrogs, are the largest known amphibians in southern Africa.
“Where I live”
African bullfrogs are found in desert, savannah, and grasslands of
sub-Saharan Africa. They remain underground during the dry season and
inhabit seasonal bodies of water during the rainy season.
African bullfrogs are a featured species in The Maryland Zoo’s Animal
Embassy collection. Zoo educators introduce African bullfrogs and
other Animal Ambassadors to audiences in education programs on and off
grounds.
“How I live there”
Make no mistake about it, this is one tough, resilient, highly
adaptable amphibian. African bullfrogs manage to withstand some of the
harshest environmental conditions imaginable, mainly by hunkering down
and waiting for conditions to change. During the dry season, which in
some parts of the bullfrog’s range could last for more than a year,
African bullfrogs stay underground in chambers that they excavate using
horny tubercles on their hind feet. While underground, they stay
relatively cool and damp but cannot feed. They adapt to this
circumstance by entering a dormant state known as estivation that is
triggered by excessive heat or drought.
Estivation is functionally similar to hibernation, only it is
triggered by excessive heat or drought whereas hibernation is triggered
by winter. In either state, the animal becomes physically inactive or
dormant, often appearing to be in a deep sleep. The animal’s breathing
and metabolism slow and its body temperature drops, allowing it to
conserve enough energy to survive for a prolonged period without food.
When the rains begin, African bullfrogs emerge from underground.
They gather in and around seasonal pools of water and spend their
relatively short active season feeding and mating.
African bullfrogs are ambush predators. They sit partially buried
with snouts exposed, waiting for some unsuspecting animal to wander by.
African bullfrogs will eat anything that they can fit into their very
wide mouths! This includes invertebrates, fish, other amphibians,
reptiles, rodents, and small birds. When prey comes within range, an
African bullfrog will drop its lower jaw forcefully, unfurl its tongue,
and snatch its meal. It makes use of “odontodes” – sharp, tooth-like
projections in the lower jaw – to secure struggling prey.
“Making my mark”
African bullfrogs are very large! Breeding males are easily identified by bright yellow patches under their forelimbs.
Raising Young
African bullfrogs breed during the rainy season. Males and females
congregate around temporary puddles and pools created by rainwater.
Males gather at the center of a pool in leks, or breeding arenas, and
make loud, booming calls to attract females. The larger and more
dominant males occupy the center of the lek, and chase away smaller
males. They can be very aggressive, often injuring or even killing
smaller males that approach.
A female frog will swim along the surface of the pond until she is
within a short distance of the males and then dive and resurface at the
center of the lek. She thus avoids the smaller, less desirable males
and goes directly to the larger ones. One male will successfully jump
onto her back and cling to her in the universal frog mating posture
known as amplexus.
The breeding couple makes its way to the shallow edge of the pond
where the female deposits her eggs. She will lay up to 4,000 eggs per
clutch. Her mate – usually the dominant male in the territory – will
fertilize the eggs above the waterline. They hatch within two days, and
it is the male who exhibits parental care. He guards the eggs and then
the tadpoles. If necessary, he will also dig channels to allow the
tadpoles to reach deeper water. The tadpoles metamorphose in three
weeks.
“What eats me”
Turtles and monitor lizards prey on bullfrog tadpoles. Birds are the
most likely predators of adult African bullfrogs. People also hunt and
eat African bullfrogs.
Conservation
African bullfrogs are not listed as threatened or endangered, but are
possibly stressed by habitat loss, hunting, and over-collection for the
pet trade.

Just thought that this was a very interesting fellow!
The last of the geese flew over heading to warmer climates! Just the locals are left now.
(They are just dots in the sky, but if you can make the video larger, you maybe able to see 'em)
When it's foggy and raining, I can't see the mountains. :o(
Charlie and the girls wanted out of the run, but it's just too muddy and I really didn't want to get my boots full of it. Needless to say, they weren't very pleased with me.
The plastic sheeting along the bottom helps keep the drafts out of the pen. When it's windy, they all hunker down in the hay that is piled behind it.
