The California Cuckoo 
the indigestible portions, such as bones, feathers and claws, is proof anew 
of the bird’s excellent digestion. 
No other bird is so bound up with the historic, romantic past of 
California. No other has so caught the fickle focus of public curiosity, 
or been rumored in so far a fame. Yet few others have been so penalized 
for such prominence. From the roisterous vaquero, who pursued the 
bird at sight, to the intoxicated possessor of the modern pump gun, who 
shot up everything in sight, the bird has suffered in cruel measure. Now 
that we have good laws, it is time to add good sense and good will, and 
so make amends for the stupid and depauperizing excesses of the older 
generations.
