▁status ▁of ▁this ▁species ▁has ▁not ▁been ▁ass essed ▁yet . ▁However , ▁under ▁the ▁IU CN ▁Red ▁list ▁criteria , ▁it ▁qual ifies ▁to ▁be ▁considered ▁crit ically ▁end anger ed ▁due ▁to ▁its ▁limited ▁home ▁range , ▁small ▁population ▁and ▁probable ▁habitat ▁de grad ation . ▁A ▁major ▁threat ▁to ▁the ▁cross b ill ▁is ▁climate ▁change . ▁The ▁cum ulative ▁hot ▁weather ▁( > 3 2   ° C ) ▁can ▁result ▁into ▁the ▁early ▁dispers al ▁of ▁the ▁p ine ▁cone ▁se eds , ▁thus ▁limit ing ▁the ▁food ▁avail ability ▁for ▁the ▁cross b ill . ▁Because ▁of ▁war mer ▁weather , ▁another ▁threat ▁are ▁mountain ▁p ine ▁b ark ▁be et le ▁inf est ations . ▁They ▁will ▁bur row ▁in ▁the ▁p ine ▁trees ▁and ▁subsequently ▁killing ▁them , ▁which ▁can ▁further ▁ex ac erb ate ▁the ▁food ▁security ▁problem ▁for ▁these ▁birds . ▁The ▁potential ▁for ▁large ▁fires ▁increases ▁every ▁year ▁due ▁to ▁climate ▁change , ▁which ▁can ▁prove ▁dis astr ous ▁for ▁the ▁cross b ills ▁if ▁a ▁significant ▁portion ▁of ▁the ▁p ine ▁trees ▁die . ▁It ▁is ▁project ed ▁that ▁the ▁l odge pole ▁p ines ▁will ▁disappear ▁from ▁the ▁South ▁Hills ▁and ▁Alb ion ▁Mountains ▁by ▁the ▁end ▁of ▁the ▁century . ▁ ▁References ▁ ▁External ▁links ▁The ▁Cass ia ▁Cross b ill ▁– ▁Id aho ’ s ▁New ▁End em ic ▁Species ▁- ▁Multiple ▁pictures ▁of ▁the ▁Cass ia ▁cross b ill ▁Cass ia ▁Cross b ill ▁Species ▁Account ▁-
