Falconry Hood Sizing

These are some of the common falconry hood sizes for birds. If you provide your bird’s sex, breed, flying weight and (if possible) head measurement with your order it will help us to accurately size the correct falconry hood for your bird.

Remember that there is variation in head sizes between birds of the same species, and that we offer a free replacement service – if you order a falconry hood that does not fit you can send it back in original condition and exchange it for a different size.

The sizes provided are for Ron Rollins Millenium blocks, Steve Tait blocks, and Slipjer’s Cannon hoods. The Rollins and Slipjer sizes are mm measurements, and the Tait size is the size of the block.

The head measurement
In addition to providing your bird’s sex, species and flying weight, it is helpful to provide the head measurement when ordering a falconry hood. This measurement is taken across the top of the head, behind the eyes as shown in the picture below.

Falonry hood sizing and returns

We ask for information on your bird in order to size the falconry hood as accurately as possible. As you can see by the above sizing list, some species of birds may typically fit a range of different hood sizes. All birds differ slightly, and sizing is not an exact science so we will accept returns for hoods that do not fit.

The returned falconry hood will need to be in the original condition. If you purchase a hood that is not the right size for your bird, please return it unused, unmarked and undamaged with details of the sizing problem and we will happily send you a new one.

Please do not hesitate to give Kevin a call on 07723442669 to discuss sizing before placing an order.
