Final answer:
The eggs described could belong to a turtle species, but without more information, it is difficult to determine the exact species.
Step-by-step explanation:
Turtle eggs are soft and have a leathery shell, which is characteristic of reptile eggs. So, the eggs you described could belong to a turtle species.
However, without more information or a picture, it is difficult to determine the exact species based on the color and location of the eggs. In Bangalore, India, there are several species of turtles that could potentially lay eggs near windows or on wood.
To accurately identify the species, it is best to consult a local expert or a field guide specific to the turtles in your region.
