What's the Difference Between a Purple Finch and a House Finch?

Male Purple Finch and Male House Finch Share the Same Tree
by Grandma Pearl
Just 2 days ago I was fortunate enough to notice both a male purple finch and a fledgling male house finch sharing the same tree branches.  If you look closely, you can see some of the differences in coloration and where it occurs on each bird.

Male purple finches (he's on the upper left side of the above picture) have a bright raspberry colored head, chest and rump.  When the sun's rays strike that rose hue just right, you're hit with the most beautifully intense rose red that is amazingly vibrant. 

House finches sport a brown patch behind their eye, and they have a brown upper back and wings.  Brown streaks mark the house finch's chest, while the male purple finch has no brown streaks on its chest.  Male house finches show a more reddish-orange coloration, which can vary through the orange shades and into the yellow spectrum, depending upon how many carotenoids they have ingested from their food. 

Their neck and upper chest, rump and stripe above the eye, and forehead are all orange.
Note, too, the difference in the tails.  Purple finches have a more deeply notched tail; house finches have a more square-shaped tail with just a slight notch.

The lovely warbling songs of the purple finches always brighten my day, especially when springtime is at hand.  House finches, on the other hand, have a less harmonious song, I think, than the purple finches.  It is, however, joyful and as bright as their warm orange color.  Both of these finches are very close in size, with the house finch being just a tad smaller at about 5-3/4 inches.

In both the purple finch and the house finch, females are heavily streaked.  House finch females are a lighter shade of brown with a brown head.  Purple finch females have a white streak behind their eye and a brown patch on their cheek.

The little house finch fledgling in my picture is just learning how to fly by making short hops from bush to tree branch.  One of the first places I saw him land, albeit a little awkwardly, was the tube seed feeder.  There he perched and dined for quite some time.  Occasionally he traded one perch for another, but seemed to be comfortable on that feeder.

How Do Birds Get Their Colors?

How Do Birds Get Their Colors?
by Grandma Pearl


Have you ever wondered why some birds have iridescent patches; or why Northern Cardinals are red; or what makes Blue Jays blue? How dull would life be without the colors that punctuate our lives?  Everywhere you look Mother Nature has given us a huge paint box full of colors; and she reserves her most diverse color palette for our backyard birds.

My two most memorable gifts were my first watch, because I have always been fascinated with the concept of time and how it surrounds and consumes us; and the industrial size box of 64 crayons!  Later on Crayola bested themselves with an even larger size, which I was very fortunate to receive as a gift as well.

Colors, especially those emanating from the natural world, nurture and feed my creative soul.  They determine in large part how I feel, whether it be happy on a sunny, green goddess day; or contemplative when the wind blows cold and grey.

So how do birds’ feathers develop their colorations? 

Pigment and how the feather is constructed determine the color of birds' feathers.  The pigments come from just 3 different groups.  To learn about these pigments and where they come from, and why blue jay feathers look blue even though they are really dark brown, click here
