Monitoring birdhouses gives you a rare glimpse into the often hidden world of nesting birds. It allows an up-close look at nest materials, delicate eggs, and birds at work. I have just two boxes on my property; bluebirds occupy one and tree swallows have taken up the other. In the week ahead, the bluebird eggs will hatch and, hopefully, the swallows will begin laying eggs; and I will have a chance to watch it all unfold.
Tips and Techniques– I experimented this week with using watercolor loaded into a dip pen to write the text. Watercolor doesn’t perform as well as ink, but it certainly works, and it opens up a whole host of color options. If you want to try it, use a brush to create a pool of the color you want and then brush the watercolor onto the nib. You’ll have to reload frequently. Try starting with one color and then altering it with another to create color variation in the letters.

For the last month, I’ve been watching a robin’s nest that sits on the sill of an eyebrow window at our house. I’ve been able to directly observe everything from four perfect eggs to four pathetic-looking naked chicks to four gaping mouths, begging for their parents to stuff them full of moths and worms. Last Sunday I made this ink sketch, added a bit of color on Monday night, and figured I finish the page later this week. But even when you count your chicks before and after they hatch, it doesn’t mean things will turn out well.
I expected to see four jostling chicks with feathers today and instead found a perfectly empty nest. I checked the calendar, checked my nest records, checked reference books, and checked again. Eleven days…just shy of the 14 to 16 days that it typically takes for nestling robins to fledge. My suspicion is that an owl made off with a nice meal. Although the birds were protected from ground predators, they were otherwise completely exposed, especially as they grew larger and began to overflow the bounds of the nest. It’s an unfortunate fate…unless, of course, you take the owl’s perspective.
Tips: If you are observing nesting birds, it’s a good idea to follow a birding code of conduct to make sure you don’t disturb the birds. The Cornell Lab of Ornithology NestWatch program is a good place to learn and to contribute your findings.
