Cassia crossbill a small area and on a singular food source is due to the lack of squirrels, the usual primary seed dispersal of the lodgepole pine. As a result, serotinous cones are especially abundant in this region, which allows cones with seeds to accumulate in high quantities that will last for decades. This has led to a coevolutionary arms race between the crossbill and lodgepole pine, as the Cassia crossbill is the primary selective agent. In result, the lodgepole pine are creating cones with thick-scaled cones, whilst the crossbills have evolved deeper bills to counter this. The seeds of younger serotinous
