Abstract:

The sudden disappearance of the White-eared Bulbul (Molpastes leucotis) from the avian fauna of Lahore presents a significant ecological anomaly. A.J. Currie's meticulous documentation in "The Birds of Lahore and the Vicinity" in 1916 provided critical insights into this species' migratory patterns and local breeding habits, indicating its historical prevalence as a cold weather visitor. However, recent records dating back 23 years reveal a startling absence of any sightings within Lahore, in stark contrast to past abundances. Notably, the prevalent Red-vented Bulbul (Pycnonotus cafer) has considerably outnumbered the White-eared Bulbul, despite being more common in the southern regions of Punjab.

This article aims to investigate the underlying causes behind the complete disappearance of the White-eared Bulbul from Lahore's ecosystem. Plausible reasons include urbanization-induced habitat loss and unfavorable alterations in environmental conditions, leading to the abandonment of once-favored habitats by this species. This investigation underscores the necessity of understanding the ecological dynamics and anthropogenic impacts driving such sudden extinctions to inform conservation efforts and preserve avian biodiversity.


Introduction:

The White-eared Bulbul (Molpastes leucotis), historically a common visitor to Lahore, featured prominently in A.J. Currie's observations documented in 1916. Its migratory behavior, arriving in October and departing in March, suggested a seasonal presence within Lahore's avifauna. Furthermore, evidence from Major Lindsay Smith indicated breeding activities in nearby regions during hot weather, hinting at the species' potential local nesting habits. However, recent records spanning over the last 23 years highlight an alarming absence of any sightings within Lahore, a stark contrast to historical observations.

Discussion:

In contrast to the declining presence of the White-eared Bulbul, the Red-vented Bulbul (Pycnonotus cafer) has shown a noticeable increase in population within the region. The shift in prevalence between these species raises pertinent questions regarding the ecological factors contributing to such a drastic disappearance. Urbanization and associated habitat loss emerge as prominent factors impacting Lahore's avian biodiversity. The transformation of natural habitats into urban landscapes, coupled with changes in climatic conditions, might have rendered the once-favored habitats of the White-eared Bulbul inhospitable, compelling their departure from Lahore.

Conclusion:

The abrupt vanishing of the White-eared Bulbul from Lahore's avian community represents a concerning ecological event. Its sudden absence, despite historical prevalence, raises concerns about the vulnerability of species to anthropogenic activities and environmental alterations.
