The leaves of the Laburnum tree had turned yellow. The seeds too had fallen down. However her body which was yellow in color made her barely visible as it would mix with the color of the leaves which too was yellow in color.

Why was Goldfinch’s body barely visible?

Explanation:

The correct answer is option 'A' - due to her dark coloured yellow body. Goldfinches are small birds with vibrant yellow plumage, and their bodies can blend well with their surroundings. Here's a detailed explanation:

1. Dark coloured yellow body:
Goldfinches have a dark coloured yellow body, which means their feathers have a deeper shade of yellow. This darker hue helps them camouflage and blend with their environment, making it difficult for predators and humans to spot them easily. The dark colouration of their feathers helps them to remain hidden and protected.

2. Camouflage:
Camouflage is a defense mechanism used by animals to blend with their surroundings, making it harder for predators to detect them. In the case of Goldfinches, their dark yellow plumage allows them to camouflage effectively in various habitats, such as meadows, gardens, and woodlands. This camouflage helps them to evade potential threats and increase their chances of survival.

3. Small size:
While the question also mentions that Goldfinch's body was barely visible due to her small size, it is important to note that the primary reason for their inconspicuousness is their dark coloured yellow body. However, their small size can also contribute to their camouflage, as they can hide behind foliage, branches, or grass, making it even more challenging to spot them.

4. Tree height:
The question also suggests that the visibility of Goldfinch's body was affected by the height of the tree. While the height of the tree might influence the perspective from which one observes the bird, it does not directly impact the visibility of its dark coloured yellow body. The camouflaging effect of their plumage remains consistent, irrespective of the tree height.

5. Brown colour:
Option 'D' suggests that Goldfinch's body was barely visible because she was brown in colour. However, this statement is incorrect. Goldfinches are not brown in colour; they have vibrant yellow plumage. Brown colour is not characteristic of Goldfinches and would not contribute to their body's visibility.

In conclusion, the correct answer is option 'A' - Goldfinch's body was barely visible due to her dark coloured yellow body. This dark yellow plumage allows Goldfinches to blend with their surroundings, providing them with camouflage and protection against predators.

She had a dark colored face with stripes on it which was quite visible. However her body which was yellow in color made her barely visible as it would mix with the color of the leaves which too was yellow in color.
