Final answer:
Robins are often associated with spring in North America. Climate change is causing birds to alter their migration patterns, moving north earlier and potentially facing food shortages, competition, and new predators.
Step-by-step explanation:
One bird often associated with spring in North America is the Robin, known for its appearance as the weather warms. However, with changes in climate, birds are altering their migration patterns and moving to areas farther north earlier in the season than they traditionally would.
This northward shift, mirrored by the increase in average winter temperatures, could lead to several problems, such as mismatches in the timing of birds arriving at breeding grounds and the availability of food resources, potential overcrowding and increased competition for nesting sites, and exposure to new predators and diseases to which they may not have adapted defenses.
Conservation efforts must take these shifting patterns into account to ensure bird populations remain healthy and stable.
