Details of this species in Aden
Source: Brook et al. 2003; Ryall 2002
Species Notes for this Location:
House crow have been long established in Aden (Ryall 1994, in Ryall 2002) and have spread to adjacent Lahej, Abiyan and then Hodeidd and El Khawka by the 1980s.
Management Notes for this Location:
A large-scale, but ultimately unsuccessful, eradication attempt against house crows occurred in Aden, Yemen, in the late 1980s (Jennings 1992, in Brook et al. 2003). Over 240,000 birds were killed (poisoned) during a 2-year, government- funded program, but a lack of comparable effort in neighboring Lahej and Abiyan meant that migration quickly replaced these losses
Disease transmission: House crows may be related to important public health problems. In one study different members of Enterobacteriaceae including Salmonella, and Shigella serotypes and Proteus strains as well as members of Vibrionaceae and Pseudomonads were isolated from a great proportion of crows. Some of them were found identical to the strains previously isolated from patients suffering from diarrhea in Aden. Giardia lamblia cysts and Hymenolepis nana ova were also recovered from crows. It was concluded that crows may participate in the spread of diarrheal diseases in Aden (al-Sallami 1991).
Economic/Livelihoods: House crows have become a major pest in the Aden-Lahej-Abiyan region due to the extremely high density that the house crow population has reached in these areas. These populations have presumably been supported by the highly available refuse, drying fish and market gardens (al-Sallami 1991).
Fouling: The house crow pollutes the environment by dropping their faecal material all over the city (al-Sallami 1991).
