Transporting your bird in cold weather: what a study on poultry trucks teaches
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Transport advice almost always focuses on heat, rarely on cold — yet both extremes threaten a bird in transit. Aldridge, Luthra, Liang, Christensen, Watkins and Scanes published a 2019 study in Animals that measures precisely what a bird experiences inside a transport compartment in winter. Our other travel guidance is gathered in the bird travel and safety section.

The protocol: twenty-eight trips, onboard probes
The researchers fitted poultry transport trucks, modified according to common industry practices (double-boarding the exterior walls of the modules), with temperature probes placed in direct contact with the birds. Twenty-eight trips were tracked on roads across the south-central United States, in both winter and summer, to map the real gap between outside ambient temperature and what the animals actually experienced.
Double-boarding helps, up to a point
In the cold season, double-boarding the walls raised the internal temperature more than eight degrees Celsius above ambient, even with outside temperatures as low as minus sixteen degrees. That is a reassuring result for good insulation. But the authors also note its limit: this elevation may no longer be enough once ambient temperature drops below zero degrees, with cold winning out despite the protection.
What this means for a car trip
A heated car cabin bears little resemblance to a poultry transport truck, but the underlying principle carries over: protection against cold has a limit, not an absolute guarantee. The fastening and ventilation precautions detailed in our article on transporting a bird by car still apply, with one extra step in severe cold: never place the travel carrier directly under a heating vent or against a window, and only switch the engine off once the cabin is warm if a stop is needed. The general guidance on drafts and cold in winter also applies during travel, not just at home.
And in summer?
The same study finds, on the heat side, that surface wetting and evaporative cooling applied at loading were enough to keep the compartment at or below ambient temperature for part of the trip — an industrial approach with no direct household equivalent, but one that confirms how much the carrier's material and ventilation matter in summer too, as detailed in our article on choosing between a plastic or metal carrier in hot weather.
Frequently asked questions
Is a simple cloth enough to insulate the carrier from cold?
A light cloth limits direct drafts but does not thermally insulate a carrier exposed to cold for long; heating the vehicle cabin remains the main protection.
Can a bird be left in an unheated car in winter, even for a few minutes?
No: the inside temperature of a parked vehicle drops quickly once the engine is off, exposing the bird to cold far faster than most people expect.
