Happy Easter Everyone!

It’s one of the most rewarding times of the year for bird feeding enthusiasts. You may have noticed a bit of a slowdown at your feeders recently but keep in mind that birds on the nest tend to gravitate to insects for a while to feed young.  I have seen about a 50% slowdown in the last few weeks, but that’s about to change.  Recent sightings of Rose-breasted Grosbeaks and Indigo Buntings at feeder’s means feeder activity will again pick-up with their arrival.

We tried to pull together an informative blog for this week but just ran out of time.  So we’ve compiled a few minutes of spring bird feeding video for you to enjoy.  Just yesterday morning I saw at my feeders the first male Rose-breasted Grosbeak of the season.  Hopefully all of you have your feeders full and ready because they are pouring into this area now and will continue for the next three to four weeks. 

In the video you will see multiple Rose-breasted Grosbeaks, male and female, at a platform feeder full of sunflower, and a lone Indigo Bunting that seems unconcerned about being totally surrounded.  You will also see a Pine warbler that has been coming to my feeder filled with our Woodland Blend.  It has visited suet feeders as well.  It may look a little like a Goldfinch at first glance but at the end of the clip you will hear its distinct Pine warbler call. 

Bluebirds love mealworms and the one in the video can’t seem to get enough in his beak.  Most Bluebirds are likely involved in their first nesting by now but if you want to attract them there is still time.  Bluebirds may nest up to three times per season.  Always start with a nest-box first.  After they discover the nest-box you may want to consider feeding them, although it’s not necessary for success.

And check out the mass of Goldfinches on the long tube feeder.  Goldfinches are in full breeding plumage now and really light up the backyard.  Note the differences in male and female coloring.  During spring migration Goldfinch numbers at your feeders can literally change on a daily basis.  Be patient and check the quality of seed in your finch feeders regularly.  Wet weather can really have a negative effect.  And finally there’s a little video of a Carolina wren feeding babies at a nest-box on my back porch.  

We at The Wood Thrush Shop want to wish you all a happy spring and Easter.  Have a great weekend and enjoy the wonderful backyard birding of spring in middle TN!

House Wren Competition

After our blog about “dealing with predators and problems” appeared last week we received a couple of comments about House Wrens (HW). One comment referred to the HW as a predator. Technically the HW is not a predator but a competitor, and has been known to pierce eggs and even kill baby birds in the nest box. They also have the unique behavior of filling up several available boxes with their nest material with no intention of using those nests. These are known as “dummy nests”. This is an interesting dilemma because the HW is a native songbird and must be treated as such.

The House Wren is not a year round species, like the Carolina Wren, and tends to first appear in this area around mid-April. They are fairly common but many of you will never see one in your yard. In 28 years at my home I have never included the House Wren on my “yard bird” list.

House Wren nest is comprised of course sticks.

HW’s use almost exclusively sticks for nest building so when monitoring your nest boxes this is an easily identified nest. Any advice we can offer to help keep HW’s from doing what they do may “backfire”. Offering more choices of nest boxes can alleviate “pressure” on the one or two already present but may encourage more HW activity. Spending a little time monitoring your boxes can help. For instance, if you find sticks in a nest box where Bluebirds have been building a nest you may remove the sticks. Don’t just drop them on the ground because HW’s will just retrieve them and put them back. Or as we suggest with House Sparrows plug the entrance hole to a box for a while if you see HW activity.

An interesting strategy to try if you have experienced HW issues is the wren guard. The wren guard disguises the entrance hole. (Click here for a more in depth look at the wren guard). The wren guard is best used after a Chickadee or Bluebird, for example, have already fully committed to a nest by laying eggs.

It’s good to remember competition among birds for nest sites can reveal some difficult things about nature.

We hope this helps some of you and next week we will spend a little more time on monitoring Bluebird boxes. Please keep the questions coming. We enjoy being able to address things you want to learn about backyard birds.
