frilled neck lizard, much like its close relatives in the agamidae
family, leads a semi-stationary lifestyle. Their morning hours are spent
basking in the sun in order to raise their body temperature, or if need
be in the shade to cool down. Frilled necks
like to have a body temperature about two to three degrees above the
atmospheric temperature. As well as basking in the morning hours you
can find the frilled neck foraging for their morning meal. After their morning meal, the frilled neck
will not feed again until late afternoon.
The activity of
the frilled neck lizard is directly correlated to the seasons and
temperature of their environment. Australia experiences a great deal of weather variety throughout the year. The most significant weather aspect
for the frilled neck is the difference between the wet and dry seasons.
The frilled neck experiences a very distinct alteration in activity and
behavior during these two seasons.
During the dry season the frilled neck experiences a
decrease in activity. Their body temperature is reduced by a couple of
degrees during the dry season to help conserve energy. Their metabolism
is slowed by about 23% due to the lack of physical activity/food, and to
conserve energy. Because of the decrease in body temperature and metabolism, the
frilled neck spends most of its time just perched in the trees. In fact
during the dry season, you will find the frilled neck perched in a tree
for 90% of the day. That equates to only about 2.4 hours a day doing physical activity such as foraging.
contrast to the dry season, the wet season brings about boosted
activity levels in the frilled necks. Their metabolism increases to
accommodate for the increased activity,
increase in food supply, and increase in available energy. There is also a sharp increase in frilled neck
population. All of these changes are due to multiple factors. With the
rainy season comes higher temperatures, higher humidity, more rain, more
available food, and the start of the mating season.
necks reach sexual maturity early in life. Around the
beginning of September, the male frilled necks will become very active in
order to attract mates. They will compete with each other, often times
fighting, opening their frills, and physically attacking each other.
Competition is often a large part of mating; therefore, only the
strongest and most fit members will pass on their genes.
frilled necks can carry anywhere from 8-23 eggs
per clutch. The frilled necks have one or even two clutches in one
mating season. The first clutch will be laid sometime in November. About
a month later, in February, the eggs will start to hatch. Each baby
frilled neck weighs only about four grams. To meet the friends and
