For many years, great studies have been done on Flamingoes especially on the Great Rift Valley lakes of Kenya and Tanzania. One of these lakes is the famous Bird watchers paradise – Lake Nakuru national park. It is here where over 1.5 million flamingoes wallow the shoes of alkaline waters rich in blue green algae. Many visitors on African Safaris are amazed with the panoramic view of the spending with great photos taken on vast African horizons and rocky cliffs.
Although
the alluring ecstasy to take more snaps is immeasurable, there is need to pick
on a frew facts about the Flamingo and why there is great need to conserve them
and their few delicate habitats.
Species
There
are 6 species of flamingoes in the world, At first glance, they may look
similar to each other, but certain features such as size, leg colour or beak
allow easy identification.
Today,
we will major on the lesser Flamingo as we explore their vast and diverse facts
as follows;
Behavior;
Flamingoes
are itinerant species adapted to respond to changes in local environmental
conditions, and thus depend on a network of suitable sites. They feed on
species of microscopic cyanobacteria and benthic diatoms found only in alkaline
lakes.
The
characteristic feeding is primarily by swimming and filtering the algae and
diatoms with a specialized bill that contains up to 10,000 microscopic
lamellae. The Lesser Flamingos depend primarily on shallow saline/alkaline
lakes, pans, wetlands and coastal areas within easy flying distance (i.e. 120-180
km) of a good feeding site for the parents.
They
feed several hours each day when the surface of the water is sufficiently calm
to enable them to feed. If the surface of the water is not calm, they are
unable to feed and are confined to the limited areas of wet mud.
Species Classification
They
are classified as “Near Threatened”, nearly qualifying as threatened under
criteria A3c: (A population size reduction of 30%, projected or suspected to be
met within the next 10 years or three generations, whichever is the longer -up
to a maximum of 100 years), based on a decline in area of occupancy, extent of
occurrence and/or quality of habitat.
It
is also listed in Columns A and B of the Agreement on the Conservation of African-Eurasian
Migratory Water birds (AEWA) Action Plan, Appendix II of the Bonn Convention
(CMS) and Appendix II of the CITES convention.
Conservation
there
are four separate populations recognized for conservation purposes;
1.
The largest population, estimated to be 1.5 - 2.5 million individuals, occurs
on the alkaline-saline lakes of the Great Rift Valley in East Africa.
Smaller
populations occur in the
2. North-western India, estimated to be
approximately 390,000 birds.
3. Southern Africa, estimated to be 55,000 -
65,000 birds.
4. West Africa, estimated to be 15,000 - 25,000
birds.
Maturity
They
reach sexual maturity at 3-4 years of age and they breed following seasonal
rains that provide the flooding necessary to isolate remote breeding sites from
terrestrial predators and the soft muddy material for nest building. Nests are
built from mud substrates where they lay eggs. The mean incubation is 28 days
and Fledging is approximately 70 days.
The
selection of breeding site is chosen in regard to; Inaccessibility to
terrestrial disturbance from humans or animal predators and subject to seasonal
flooding that is sufficiently shallow (and calm) to enable the construction of
the traditional conical mud nests without them being washed away, but sufficiently
deep and long lasting to prohibit terrestrial predators from reaching the
nesting colony.
Threats to flamingo
conservation
Most
critical threat to the survival of the Lesser Flamingo (a factor causing or
likely to cause very rapid declines >30% over 10 years or three generations)
is the degradation of its specialized breeding and feeding habitats through
1. Altered hydrology and
water quality
2. Wetland pollution,
3. Extraction of salt
and soda ash
4. Disruption of its few
breeding colonies by human activities
There
are also threats of High importance (factors causing or likely to cause rapid
declines (20-30% over 10 years or three generations)
•
Poisoning
(heavy metals, pesticides & cyanobacteria toxins)
•
Diseases
– Avian flu, cholera, mycobacteriosis
•
Disruption
of its few breeding colonies by human activities (particularly from nearby
settlements).
and
finally, threats of low importance (factors causing or likely to cause
negligible decline)
•
Human
disturbance of non-breeding sites
•
Collision
with man-made structures
•
Predation
•
Competition
with other species for food and breeding sites
•
Harvesting
of eggs and live birds.
Therefore,
while doing your African Safari, please take time and give back to the
conservation of this endangered jewel while at the same time minimize any
interference that may contribute to them being more endangered.
Enjoy
your view of Flamingoes!
