They Are Coming. Are You Ready?

Daylight saving time is only a few days away and spring is right around the corner. The chickadees have been calling hey sweetie since late January preparing for the coming nesting season, while many migrants are already heading north--grackles, blackbirds, robins, and phoebes are some of the earliest to depart their winter territories. Of the approximately 650 species of birds that nest in North America, the vast majority are migrants. Thus, ready or not, the birds are coming.

Spring migration fills backyard enthusiasts with the greatest joy as they watch new arrivals scouting out the best places to forage, feed, rest, and nest. However, for the birds themselves, this is one of the most physically stressful times of the year. Birds are constantly battling unpredictable weather, predation, the energetic demands of molting to breeding plumage, and the unknown availability of food and water. As gardeners we have a vital role to play in supporting our avian migrants. Studies have found that yards, especially in urban and suburban areas, have a significant impact on the nesting success rate and abundance of birds.

The following are some ideas to help support birds in the early spring:

  1. DELAY SPRING CLEANUP Often the first migrants to arrive are seed eaters. They are looking for remnant seeds in trees, on dead flowers, and beneath the leaf litter around your garden beds. Leave your gardens messy until late spring to help provide optimal foraging conditions. Explore YardMap for more ideas on growing seed-producing flowers for birds.

  2. BIRDHOUSES Birds begin scouting optimal nesting areas the minute they arrive in their mating territory. And for year-round residents, this process can begin as early as January or February. Put up your nest boxes as soon as possible so birds know their options for mating season.  For more information on appropriate birdhouses to use, visit Nestwatch.

  3. MUD PUDDLES These are not just for kids, but birds too!  Mud puddles are a great way to provide both water and nesting material for birds. Robins, phoebes and swallows all use mud to build their nests. So, find a wet area in your yard, dig down about six inches, let the water fill in, and watch the birds celebrate!

  4. DON’T USE PESTICIDES OR HERBICIDES As spring gets underway and soil temperatures reach 40 degrees Fahrenheit, earthworms, beetles, and insects become active. These organisms feed a multitude of birds and applying pesticides or herbicides to your lawn, gardens, shrubs, or trees will often kill these insects, leaving less food for the birds. Once birds are nesting, they rely heavily on insects--even seed eaters such as chickadees and nuthatches--for protein-packed snacks for their offspring.

Following these simple strategies will help provide a welcoming and nourishing backyard for avian migrants in early spring. To learn more about how to prepare your property, explore our Learn pages. The birds are coming, are you ready?

Purchasing Spring Seed

There are so many seeds and seed companies to choose from!  Choosing seeds can be an adventure for those that like to spend hours ogling over seed catalogs. But, it can also be a burden when time is limited and you are trying to make the best choices about which native seeds to add to your property. Let us help. We've created short descriptions of mail-order seed distributors across the U.S. and provided some examples of native seeds or plants they sell, any of which will make a great addition to your backyard.  To read this article, view our Citizen Science Blog. Happy planting!

Update on Native Bumblebee Research

A new study published in the The FASEB Journal last month revealed new findings on the effects of neonicotinoids on native bumblebees.  To date, much of the research has focused on the impact of this pesticide on honeybees, but now attention is turning to the effects of these chemicals on native bees. Early findings reveal that, "Chronic exposure to neonicotinoids increases neuronal vulnerability to mitochondrial dysfunction in the bumblebee," which results in poor brain function and defects in colony growth.

Catios: An Option for
Cat and Bird Lovers

That's right, catios are cat patios for those that love cats and birds. Pet owners often face the dilemma of whether to let their feline friend outside for part of the day. Some have found a happy medium by building a catio for their cat. The designs vary depending on the features you think are the most important for your feline. For creative ideas on catio designs, explore our Pinterest page. Your cat can still enjoy the "outdoors,", lay in the sunshine, and watch birds.
