Budgerigars are considered nomadic birds. They are known to move in search of food and water, and their movements are often influenced by changes in weather and resource availability. While they do not have a set migration pattern like some bird species, they are not sedentary and can cover large distances in search of suitable habitats. **

It is unclear what is meant by "birds are behind birds" without further context. It could refer to birds following other birds in a flock, birds being positioned one after the other in a line, or birds being hidden or obscured by other birds. The interpretation would depend on the specific situation or scenario being described. **

The animal that bites off canary birds' legs is the domestic cat. Cats are natural hunters and may see canary birds as prey, leading them to attack and injure the birds. It is important to keep canary birds in a secure enclosure or away from any potential predators like cats to ensure their safety. **

Birds may not get off the road because they are focused on finding food, such as insects or seeds, that may be present on the road surface. Additionally, birds may not perceive vehicles as a threat due to their evolutionary history, as they have not evolved to recognize cars as potential dangers. Furthermore, birds may be attracted to the warmth of the road surface, especially during cooler weather, which can make them reluctant to leave. **

You can drop off injured or orphaned birds at your local wildlife rehabilitation center or animal rescue organization. These facilities have the expertise and resources to care for injured or orphaned birds and provide them with the necessary medical treatment and rehabilitation. It's important to contact the facility beforehand to ensure they have the capacity to accept the bird and to receive instructions on how to safely transport the bird to the facility. **

Birds have complex cognitive abilities and are capable of problem-solving, learning from experience, and using tools. They can exhibit behaviors that suggest they are capable of thinking, such as planning for the future, recognizing themselves in a mirror, and even displaying empathy towards others. While their brains are structured differently from mammals, birds have shown impressive cognitive skills that indicate they are capable of some form of thinking. **

Birds do not have a separate urinary system like mammals do, so they do not pee in the same way. Instead, birds excrete waste in the form of uric acid, which is combined with their feces and expelled together. This mixture is often seen as a white, chalky substance. So, while birds do not pee in the traditional sense, they do excrete waste through a different process. **

No, birds do not have the ability to spit like humans do. Birds do not have salivary glands in their mouths like mammals do, so they do not produce saliva in the same way. Instead, birds have a specialized gland called the uropygial gland near the base of their tail that produces an oily substance used for preening and waterproofing their feathers. **
