Overview

• City officials say five swans remain unaccounted for from their usual stretch of the Avon River/Lake Victoria.
• One swan was located in a north-end stormwater retention pond, and crews are feeding it to build trust before attempting capture later this week.
• The parks and forestry manager first noticed three of the usual six swans missing, then found all six gone the next day with no trace.
• The city does not use tracking devices and is urging residents to call in sightings as searches continue along the river, the nearby golf course and stormwater ponds.
• The cause remains unclear, with officials considering possibilities such as human removal, a flight if wing alterations failed, or the birds being startled downstream.
