This contrasts with the results of Birgersson & Ekvall (1997), who recorded greater masses at fawns at the beginning of the fawning
Since it was unknown how spectrally distinct the fawning habitat was, training sets were developed with the maximum number of distinct signatures.
For the 1990 image, characteristics of 14 known fawn bed sites obtained from radio telemetry (Canon 1993) were used to build a signature for the fawning habitat.
Thick brush and perennial grasses provide the best fawning cover.
Plum, sumac, blackberry and certain other shrub species also can provide fawning cover.
However, most of the No contact messages occurred earlier in deployment and these can be ignored because the fawning season was quite restricted ([approximately equal to] 18 May-12 June).
For VITs, the functioning of this system is conceptually straightforward in that when the VIT is expelled at fawning, its temperature drops and it stops moving which causes it to go into triggered mode.

Since the growing season's length affects fawning
, it follows that the best time of the year for fawning
also affects timing of the rut.
Obviously, good fawning
cover equates to higher fawn survival.
We've chosen to just breed does in our research pens, then carefully monitor them the following spring to mark the exact dates of fawning
. In this way, we've been able to determine impacts of nutrition and age on birth dates.
After the winter stress period ends, the fawning
