Old World Sparrows
Passeridae
The Resilient Urban Survivors: Old World Sparrows (Passeridae) are small, social birds found across Europe, Africa, and Asia, with some species introduced worldwide. Unlike New World Sparrows, they are closely related to weavers and finches, sharing a preference for open habitats and human settlements. The House Sparrow (Passer domesticus) is the most famous member, thriving in cities and villages across the globe. Despite their reputation as common backyard birds, their populations have declined in some areas due to habitat changes. The Eurasian Tree Sparrow (Passer montanus), with its distinct chestnut crown, is another widespread species often found in rural landscapes. Sparrows are primarily seed-eaters but also consume insects, especially during the breeding season. Their adaptability allows them to nest in tree cavities, buildings, and even rooftops. In some cultures, sparrows are seen as symbols of resilience and companionship. While many species remain abundant, habitat loss and pollution affect some populations. Their close association with humans makes them an everyday but essential part of the avian world, reminding us of nature’s ability to adapt to change.
