Populations of blue-winged warblers, a type of bird, migrate south in the winter and return to canadian breeding grounds in the spring. as global temperatures have increased due to climate change, spring has started arriving in the warbler's breeding grounds earlier in the year, before the warblers return. warblers now arrive at their breeding grounds too late to select ideal nesting sites and to feed on important early-spring food sources how are populations of blue-winged warblers most likely to be affected by the earlier arrival of spring? o a. populations will go extinct since the warblers will stop migrating to breeding grounds. b. populations will be unaffected since most species can quickly adapt to effects of climate change. c. populations will increase since warmer temperatures are generally beneficial to survival, d. populations will decline since individuals will be less likely to successfully reproduce, reset next

For the most part the birds will be negatively affected by the early spring, they won't have the food they need and because they missed finding ideal nesting spot one of two things will happen, they will either pick an unsafe nesting area which can result in their young being hurt or even themselves, and/or they won't breed at all and because of this the Warbler population will decrease due to low mating rates. Eventually, the birds will evolve in a way and start coming back from their migration earlier than previous generations and thus they will have access to the food and nesting areas that they need and the population will spike again.

I hope this helps you out a little!

it will have to be B. Populations will decline since individuals will be less likely to successfully reproduce. because they will not be able to breed with other birds on the breeding grounds.

Populations will decline since individuals will be less likely to successfully reproduce. Hope this helped

Explanation:

Populations will decline.

Explanation:

Since individuals will be less likely to successfully reproduce, and because they will not be able to breed with other birds on the breeding grounds.

Hopefully this helps :)

The correct answer would be option B.

Due to the early arrival of springs, the warblers could not find ideal sites for nesting.

In addition, the early-spring food sources also get depleted by the time they reach breeding grounds.

Consequently, the reproduction and survival rates of the warblers would decrease.

Ultimately, the population size of the warblers would decrease.

answer C

Populations will be unaffected since most species can quickly adapt to effects of climate change.

answer C

Populations will be unaffected since most species can quickly adapt to effects of climate change.
