Abstract
The nest composition of Himalayan Bulbul Pycnonotus
leucogenys was studied in a village of Chamba district in Himachal Pradesh.
The observations were carried out during the month of July 2024. The various
parameters of the naturally dried nest such as shape, size and weight along
with number, weight and types of constituents formed the nest were studied. The
photographic evidence was recorded with the help of a digital camera (Nikon
Coolpix A900) and measurements were done with the help of a measuring tape and
an electronic weighing balance. The observations were as follows: height of the
nest above the ground: 3.2 meters; weight: 4.78 g; size: outer dimensions L 11 cm
x W 10 cm x H 6.0 cm; inner dimensions L 7.6 cm x W 7.6 cm x D 4.0 cm. The nest
structure consisted of dwarf shoots/branches of Indian Gooseberry Emblica
officinalis (87), sticky fruit bearing shoots/branches of Barbed
Forget-Me-Not Cynoglossum wallichii (44), inflorescence bearing
shoots/branches of Congress grass Parthenium hysterophorus (4) and
another grass (5), plant stem fibers (30), plant root / rootlet fibers (25) and
thin plastic fibers (5). The length of constituents forming the nest varied
from 6.3 cm to 27.9 cm and the average length of most of the constituents was
14.2 cm to 16.7 cm. Out of 3 eggs laid in the nest, only one hatchling could
develop up to fledgling stage. The present study reveals that the nest
composition of Himalayan Bulbul consisted of 7 different types of constituents
out of which higher percentage was contributed by shoots/branches of plants
followed by stem fibers & root/ rootlet fibers of plants, lesser number of inflorescences
bearing shoots/branches of grasses and a few plastic fibers.
