An aerial vehicle may include adjustable shrouds to selectively provide protection for propellers of the aerial vehicle. The adjustable shrouds may be moved to an extended configuration around a periphery of one or more propellers during generally vertical flight or hovering operations, when delivery a payload, and/or upon detecting objects in proximity. Likewise, the adjustable shrouds may be moved to a retracted configuration that eliminates or minimizes adverse aerodynamic effects during generally horizontal flight operations, when operating at high altitude, and/or upon detecting no objects in proximity. The adjustable shrouds may include various designs, such as fan shrouds, telescoping shrouds, folding shrouds, and deployable arm shrouds.
