Main differences between altricial and precocial birds. 1.1 Precocial vs. altricial developmental mode Conjecture 1: There is no sharp altricial/precocial dis-tinction between species, nor a continuum of cases, but a spectrum of capabilities, with many discontinuities. Altricial animals produce large number of offspring with a relatively small energetic investment in each one; therefore, the offspring are born pretty weak and many will probably die. semi-altricial birds, the time needed to get fully feathered Turkey https://www.avianreport.com/wp-content/uploads/2018/08/AlticFood-2optimized.jpg, https://www.avianreport.com/wp-content/uploads/2018/08/AlticFood-2optimized-150x150.jpg, altricial,altricial-precocial birds,nesting birds,precocial. found in the young of gulls and terns.
