Thanks, everyone for the overwhelming response
to the “Diwali for All” blog. The thought of uplifting the villagers received a huge round
of applaud and many of you have shown the positive response for helping them in the future as well. On behalf of the villagers and our wildlife group big thanks to each one of you.
Let me start today by wishing you A very happy and prosperous new year. After the festival, I am opting to start with a bird we all know by name but in reality, many don't know them correctly so I will brief you on Eagle, in particular, I will be talking about Crested Serpent
Eagle because there are around 19 popular species of eagles out of 60 various
types hence picking up one of them here.
The
Common Mistake
As I said we all know this bird by
name but we do not know this bird in reality, the most common mistake we do is
we consider all raptors as an eagle. Commonly found Kites are always known as an eagle, (we teach our kids the same) until I started wildlife I used to do
the same mistake. Buzzards, Kites, Shikra, etc are always treated as “Eagle” so I
decided to pick up Eagle as a topic to clarify the common mistake we do. Crested
Serpent Eagle was my first sighting on entering my first wildlife safari at
Nagzira, so it is closed to my heart. During this trip itself, Jogi educated me that Eagle is different from Kite and
updated some facts of this bird, which I will update you in the next section.
Facts

The crested serpent eagle also is known as
Spilornis cheela is a medium-sized bird of prey that is found
in forested habitats across tropical Asia
There are considerable variations and some
authorities prefer to treat several of its subspecies as completely
separate species. In the past, several species including the Philippine serpent eagle (S. holospila), Andaman serpent eagle (S. Elgini) and South Nicobar serpent eagle (S.
klossi) were treated as subspecies of the Crested serpent eagle
The crested serpent eagle, as its English name
suggests, is a reptile eater which hunts over forests, often close to wet
grassland for snakes and lizards, It has also been observed to prey on birds, amphibians,
mammals and fishes
A radio-telemetric study of the species in
Taiwan found that the birds spend 98% of the day perched and usually finding
food in the morning hours. They appear to use a sit and wait for foraging strategy
Crested serpent eagles are
medium-sized raptors. They range in length from 55 to 76 cm, and their wingspan
ranges from 109 to 169 cm
They can weigh anywhere from 420 to 1800 g. When
perched, an adult appears overall dark brown with an almost black 'hood' on the
head and neck. The breast and belly are brown with white mottling. The crest is
black with some white flecks is very prominent when raised
Crested serpent eagles mate in
monogamous pairs and remain in pairs throughout the year. Courtship displays
consist of pairs soaring and calling together. These courtship flights may
include rolling and wing vibrating
Crested serpent eagles communicate
with one another using vocal cues and aerial displays. Their courtship display
is complex involving multiple diving runs and mutual soaring with the head and
tail feathers raised
Crested serpent eagles eat a
significant amount of snakes, including species harmful to humans. They also
eat small rodents that can have adverse effects on crop production
I hope now you will easily distinguish
between an eagle and other raptors, for easy reference, you can check out DSLR

Feel like we should meet you and Jogi to know more about the Birds and Animals.
ReplyDeleteThanks Ramulu. Anytime you can meet us.
DeleteGood write-up. When you talk about wingspan please also include a picture of Eagle with wings spreaded. Hope you will in the next blog post about how to differentiate between eagle, buzzard, raptors, kite, shikra etc. It would be great understanding if you could post the pictures alongside the description for visual differentiation. Thank you!
ReplyDeleteThanks so much for your suggestion. Will work out on the same in upcoming blogs. Next blog will try with some comparision between these birds
DeleteMany thanks
