Spring Migration

Spring Migration is in full swing which means there will be a lot of interesting birds to see if you spend a little time looking around your yard, or at any of our wonderful parks and greenways. If you are going out for your morning, or afternoon walk don’t forget your binoculars because the neo-tropical migrants are passing through, or arriving in middle Tennessee every day on the way to their summer breeding areas. Warblers, Vireos, Blue-gray Gnatcatchers, Tanagers, Swallows, Hummingbirds, and many other species are there for the viewing if you try. Early in the morning, between 6 am and 10 am are best to see some of these birds because many of them migrate at night then settle down in the mornings to feed and rest.

The first Ruby-throated hummingbirds to arrive or pass through TN have already been sighted. Usually one, maybe two hummingbird feeders at this time of year is enough. Don’t bother filling your feeder to full capacity at this time as the feeders are of little interest to them this early.

In the coming weeks at your feeders expect to see the always popular Rose-breasted Grosbeaks and Indigo Buntings. Of course American Goldfinches are here in abundance year round but are now putting on their bright yellow spring plumage.

RB Grosbeak males are quite handsome with their black and white plumage and v-shaped splash of red on the chest, while females are brown and white with heavy streaking. Both have the distinguishable heavy beak. These birds may be seen in good numbers at your feeders. In years past I’ve seen as many as a dozen at a time, or some years just a few. They are fond of several types of seeds and feeders. Sunflower and Safflower are the more preferred seeds, while platform, hopper, and tube type feeders all work well. Let us know when you see one.

Interestingly there are still good numbers of our winter visitors like Purple finch, Pine Siskin, and even Red-breasted Nuthatches in the area.

Reports of Bluebirds with completed nests and with eggs are sprinkling in. It’s still relatively early and plenty of time to attract Bluebirds to a nest box. In years past I would not see a first Bluebird nest until late April.

Spring birding class

There is still time to register for Richard Connors bird identification class at Radnor Lake this spring. The 5-week class runs Tuesday mornings from April 9th to May 7th, and includes classroom sessions and morning bird walks. Radnor is a premier location for spring migrants and those migrants are often heard more easily than seen, so this spring class will emphasize "birding by ear". We will work on bird identification by sound as well as by sight. The class is open to beginners, but some prior knowledge of our local birds will be helpful. There is a fee for the 5 week class with part of the proceeds going to Friends of Radnor Lake.

For more information see this web page:

Differences in Ruby-throated Hummingbirds

The differences in male, female, and juvenile Ruby-throated Hummingbirds are subtle but if you know what to look for you can identify between the three fairly easily. Keep in mind that from the beginning to the middle of the hummingbird season (mid April to mid July) you won’t be seeing any juvenile birds. After the young leave the nest in July they will be considered an adult bird but with juvenile plumage.

Adult male hummingbirds of course have the ruby throat but it is not always apparently red. In certain lighting or at certain angles it can appear black. Adult and juvenile females have a white throat that is sometimes marked with faint grey or buffy streaking. Juvenile males may also have a white throat like a female, but more often it is streaked to a greater or lesser degree with black or green.

Tails are also a good way to tell birds apart. Adult males have a more forked tail with pointed outer feathers that are solid black. Females and juvenile males have a blunt rounded tail that is mostly black with white tips to the outer feathers.

Both sexes, adult and juvenile can vary slightly in size and weight depending on the time of season however it is not uncommon for birds to almost double their weight in August and September in preparation of the fall migration.

Notice the difference in the male and female tails. The male is forked where the female is blunt with white tipped feathers.

Adult female Ruby-throated Hummingbird. Notice the light spotted throat compared to the male on the right.

This adult female is showing off her more blunt tail with white tipped feathers. The male is more forked and lacks the white.

In some lights the throat of the adult male can appear black.
