Abstract

Pied crow (Corvus albus) is a widespread scavenger in urban areas of Cameroon that plays an important role in the management of solid waste. However, little is known about the factors influencing its scavenging behavior. This study explored the role of photoperiod on the scavenging activity of pied crows on solid waste materials in Bonaberi. Observations were conducted over a 4-month period to document the scavenging behavior of these birds during different photoperiod conditions (morning, afternoon, and evening periods of the day). Data collection was done within the first 15 days of each month, from 7:00am – 6:00 pm.The study has shown that photo-period significantly associated with congregation behavior of birds X2=17.737 df=8 P=0.023, birds activity X2=8.669 df=6 P<0.05,and food-type X2=52.257 df=10 P=0.000 respectively. The study also revealed a significant relation between photo-period and human activity at dumpsites r=0.100 P=0.021. More so, grouping behavior of birds significantly associated with automobile traffic intensity X2=10.120 df=8 P<0.05.Pied crows (Corvus albus) in Cameroon exhibit a strong tendency to aggregate at the solid waste dumpsites, often forming large flocks numbering in the hundreds or even thousands of individuals. Furthermore, grouping behavior of birds significantly associated with human activity X2=12.069 df=8 P<0.05.Pied crows are highly adaptable and opportunistic scavengers that have flourished in urban environments, particularly in the presence of dumpsites. By integrating an understanding of crow ecology into waste system design and operations, municipalities would leverage the valuable ecological services these birds provide while also mitigating any potential nuisance issues. Additionally, these findings acknowledge that photoperiod is an important environmental cue influencing the scavenging ecology of pied crows in urban Bonaberi. Understanding these patterns would inform strategies for managing solid waste and crow populations in growing cities. Further research is needed to explore other factors that may interact with photoperiod to shape crow scavenging behavior
