Floating Nest


Building nest out in the water seems to be impracticable but it is a fact.Several birds build nests which are surrounded by water and even floating in water. Birds like Coots build build such type of nests having a foundation of vegetation, which reaches the ground below.Water birds like Grebes build nests which are basically floating on shallow water though they are often anchored at one or two points.However totally floating nest are bulid by Jacanas and Marsh Terns.The floating nests often sinks into the water while the bird
is sitting for incubation, but due to water proof eggs the chicks easily come out without any harm.

Nesting Behaviour of Birds

Nesting Behavior of Birds


There is a common misconception that Birds build nests to live in it. It is not true. The fact is that birds build nest to lay eggs, raise their chicks, protect them from predators and adverse climate. Birds are notable for their instinct to build nest like humans and other animals. The nest varies from no nest (e.g Pratincoles) to very complex nest ( Baya weaver).

The nesting behavior of birds, the shape and size of nest varies according to their habitat, climate, breeding season, size and physiology of bird and amount of threat by predators. Broadly the nests can be divided into 12 categories.

1. No nest/ scrap nest

2. Simple twig nest

3. Cup nest

4. Cup nest with roof

5. Ball nest

6. Hanging / very complex nest

7. Mud nest

8. Hole nest in ground

9. Hole nest in tree

10. Floating nest

11. Edible nest

In my upcoming posts I will deal details about the individual nests.Birds are notable for their ability to build their nests most skillfully.

Sunbird


Fig. This is a purple rumped sunbird

Sunbirds are colourful, attractive small passerine birds. and readily enter gardens where flowering plants are planted to attract them. The sunbirds and spiderhunters belongs to family Nectariniidae. The family is distributed throughout Africa, southern Asia and northern Australia.The sunbirds have two close relatives, the hummingbirds of the Americas and the honeyeaters of Australia. The resemblances are due to similar nectar-feeding lifestyle.There are more than 100 species of sunbird in 15 genera.Two most common species seen in India are Purple Sunbird (Nectarinia asiatica) and Purple-rumped Sunbird (Nectarinia zeylonica).When one sees them feeding nectar on flight can easily be confused it as Humming bird.However we have no Humming birds here in India.Sunbirds are frequent visitors to gardens where flowering plants are present.They also built their nest in backyard gardens .

Red-vented Bulbul,The Nesting



The breeding season of Red-vented Bulbul is from March to July.It builds its nest at the fork of a branch of tree or bush generally at a height of around 2-5 m (7-15 ft). Nests are occasionally built inside houses.The nest is cup shaped built with rootlets. Mostly three eggs are found which are pinkish in color blotched with brown.Both the parent incubates the egg for a period of 15-18 days. The chicks remain in nest and are fed for about 10 to 12 days by both the parents.They keep the nest clean by swallowing the fecal material.

This nest in above photograph is built in a Bougainvillea plant in my friend's house just in front of the main gate. I watched it regularly and taken few shots without disturbing the bird.This photograph is taken by my Nikon F801 camera with a 200 mm lens.This is a bright example of man and wildlife thriving side by side.Enjoy the bird watching and know the bird in your back yard.

Asian Paradise Fly catcher, The nesting



Nesting Season of Asian Paradise flycatcher is generally June to August i.e the rainy season.It may be due to availability of more flying insects during this period.

The nest is conical in shape and just the size of a tea cup.It is found hanging from a tip of a small and thin branch of a tree generally at a height of 8ft to 15ft from the ground. The nest is woven with fine grasses and fibers.The outer wall of nest is plastered with cob webs and spider egg shells. It is observed that the female alone built the nest.The female generally lays four numbers of pale pink colour eggs with blotches of reddish brown.In some cases three eggs are also found. Incubation takes nearly 18 days and both the parent incubate the eggs alternately.The nestling period is around 10 to 12 days.The chicks are raised by both the parents.

It is quite thrilling to watch the parents feeding the nestlings.I observed it very close to the nest.The photograph is taken by my pretty old Nikon 801 camera with a 200 mm lens.Watching nature so close is a rare experience to share.Enjoy the bird Watching.
