She and other advocates warned that increased heat waves will result in long-term problems for the West Coast fauna.

Liz Hadly, a senior fellow at the Woods Institute for the Environment at Stanford University, told ABC News that nesting seasons tend to align with times of the year that weren't hot.

\"That mismatch of the nesting period of the bird and the rising temperatures is offset. When you factor in that developmental phase of being fed in the nest and not able to leave the nest, this makes them sitting ducks,\" she said.

The ecological shift could lead to several dire outcomes including, longer fledging periods for the baby birds and a decline in the number of birds that make it to adulthood, according to Hadly.

\"Their nesting success may decline,\" she said.

Seavy and the other experts said that this should propel everyone to work on combating climate change because once the bird population is negatively affected, it won't take long for other animals to suffer as well.

\"Birds tell us the impacts of climate change are serious,\" he said. \"We have to recognize that we have to address the changes for both wildlife and people.\"
