A specimen of the European cuckoo (Clamator glandarius) has recently been observed in the lower area of the Sierra de Crevillent, in Baix Vinalopó, feeding on pine processionary caterpillars. This scene, documented by the SIO, underscores the relevance of birds in ecosystem balance and their direct role in controlling species that affect pine forests.
The bird was recorded inserting its beak into one of the silk nests that the processionary moth builds in white pines. Inside, dozens of caterpillars are concentrated, which, in this case, serve as food for this species. This natural behavior makes the European cuckoo an active agent in regulating these populations.
“"The presence of insectivorous birds is fundamental for maintaining the balance of forest ecosystems, as they help to naturally reduce the proliferation of species such as the processionary moth. These processes are constant, although they often go unnoticed by most of the population."
The pine processionary moth has increased its presence in recent years, not only in the Sierra de Crevillent, but also in other enclaves of the Elche area such as the Elche Reservoir or areas near the El Hondo Natural Park. SIO specialists point out that climate change is favoring this phenomenon, with milder winters and higher temperatures allowing the species to complete its cycle more easily.
Beyond environmental value, the action of these birds has a direct impact on human well-being. Natural insect control reduces the need for chemical treatments and contributes to the conservation of natural spaces. The image of the European cuckoo feeding in a pine forest in Baix Vinalopó symbolizes that silent balance that sustains ecosystems.
