How are populations of blue winged warblers most likely to be affected by the earlier arrival of spring

Because of the early coming of springs, the warblers would not get the best places for nesting. With this, the early-spring food sources also get declined by the time they reach the breeding grounds. Subsequently, the survival and the rates of reproduction of the warblers would also get diminished. Eventually, the population size of the warblers would see a decline.

it's unlikely a majority of a large population would agree on issues

hope this : )
