Final answer:
A hummingbird nest is difficult to locate due to its tiny size, high and inaccessible locations, camouflage properties, and the protective nature of hummingbirds.
Step-by-step explanation:
Finding a hummingbird nest can be quite difficult due to several reasons. Firstly, hummingbird nests are extremely small, about the size of a walnut, which makes them hard to spot. Secondly, these birds often build their nests in places that are high up in trees or shrubs, making them difficult to reach or see without special equipment. In addition to this, Hummingbirds use materials like lichen and spider silk to camouflage their nests, making them blend in with their surroundings. Lastly, they are protective creatures and tend not to return to their nests if they feel threatened or If there are humans regularly passing by, making it hard to find when they're actively in use.
