backyard dinosaurs #4

today's backyard dinosaurs focuses on diversity...


while looking out at the bird feeder today i saw a whole bunch of different types of birds. from left to right was a house sparrow (Passer domesticus), ruby-crowned kinglet (Regulus calendula), and purple finch (Carpodacus purpureus).

this got me thinking to how many different birds live together in just the yard! you'd think in such a small space they won't have enough different things to eat or roles to play. yet even just in my bird feeder they were all able to find different seeds to eat, and each went about eating them their own way! (the kinglet wouldn't have been able to eat if not for the sparrow kicking lots of seed out of the feeder for example... where the finch was able to do its own thing regradless of the other two).

so next time your out and about look at all the different birds that live in the same area, and thing about how they all coexist and interact with one another!
