Birds, like many animals, time their breeding to coincide with the most favorable conditions in nature. This primarily relates to food availability. The late spring and early summer, when nature bursts with diversity, provide abundant food sources.
However, the recent cold and rainy weather in May has significantly reduced the insect population, crucial for feeding young birds. This has led to fewer insects and their larvae than usual, impacting the birds' ability to find food for their offspring. This year's bird broods are expected to be smaller than usual.
The adaptability of nature can cushion short-term deviations. However, climate change is causing more frequent and extreme weather variations, making it increasingly difficult for even the most adaptable species to cope.
