As part of our Bird Atlas project, Spring sent over this list of tips on how to confirm that birds are breeding. It’s pretty interesting to slow down and watch birds and connect with what they’re up to. Nature can be pretty wild ;)

She found these tips in the San Diego Bird Atlas:Great-Blue-Heron_Joanne_Bradbury

• The first thing to focus on when you see a bird is the bill. Is the bird carrying nesting material or insects? For the majority of species, carrying nesting material or food for young is behavior confirming breeding. Watch the bird for a minute or two to see whether it’s carrying the prey back to a perch to be killed and eaten by the adult itself. If the bird carries the prey any distance or is accumulating insects in its bill, it’s likely the food is destined for young.

• Find a likely spot with a few birds flitting around, sit silently for 5 or 10 minutes, and see what pops up—often quite a lot. Hurried hiking and crashing through brush will generate almost nothing. Once you spot a bird, stay with it for a moment to see what it does.

• Seemingly odd behavior may be a clue to something interesting. For example, swallows don’t normally land on the ground except to pick up nesting material (grass for nest-lining in the case of Rough-winged Swallows as well as mud for Cliff Swallows).

• Listen for unfamiliar calls—especially if they sound like those of baby birds. Even if you don’t see the young, the adults usually give themselves away with alarm calls or distraction behavior. The calls of fledglings are just as distinctive to species as those of adults and can be learned with practice. If you do discover a nest, don’t linger too long – so not to stress out the birds or attract predators.

• Spread your effort throughout the day. In the first hour or two after dawn the adults are often too preoccupied with feeding themselves and advertising their territories to engage in much breeding-related behavior. Later in the day may present good opportunities to see behaviors such as nest-building and feeding of young.

If you or someone you know owns any land in Loudoun County that can be made accessible to atlasers please let Spring know: sligi@loudounwildlife.org

Spring Ligi, our Loudoun County Bird Atlas Coordinator, just sent over some great highlights from the data that rolled in from our atlas volunteers through June. We’re getting some really exciting information on birds that we didn’t realize nest here.

Tree_Swallows_Joanne_BradburySo far, 28 enthusiastic atlasers have spent 634 hours in the field documenting 7,539 sightings and have recorded 177 species, with 74 of these species having a confirmed nesting status. 

If you’d like to join in this important citizen science project, we could certainly use your help! More information can be found on our Bird Atlas Page. Every bit of data – from backyards to large untouched areas is important to this project.

June Highlights

• Little Blue Heron – observed a Little Blue Heron, a Species of Special Interest, at the Dulles Wetlands.

• Cerulean Warblers – heard 3 singing male Cerulean Warblers, another Species of Special Interest, singing from the same point in the Ashby Gap area and then heard another one nearby.

• Black-billed Cuckoo – documented this species as a Possible Breeder in separate parts of the county (Unison and Ashburn areas, respectively) – this species is not previously thought to nest in Loudoun County!

• Dickcissel – documented this species as a Possible Breeder in the Arcola area.  This is most likely the first reported Dickcissel in Loudoun County this year!

• Red-headed Woodpecker – observed a pair flycatching and then returning to a nest cavity in the Bluemont area to feed young.

• Screech Owlets – observed 2 curious owlets nesting in a cavity in a Black Locust tree on property in the Bluemont area.

Here in Loudoun, we are fortunate to have a lot of streams that run through our yards, neighborhoods and wild places. For some fun, you try your hand at the Loudoun Streams wordsearch puzzle. Then, come on out and join us in stream monitoring - its a great time outdoors and really interesting to see all the different creatures that live in our streams.

More puzzles on Loudoun nature and wildlife can be found on our Educational Resources page.

There is a special place in our yard where heaven has met the earth.
This heaven is a swirl of azure, cerulean, sapphire and cobalt.
In it, the whispering wind sings a delicately soft “turlee”.
This heaven flashes an eternal sunset of crimson set on ivory.
It sees with sharp eyes of midnight ink.

Many of you probably heard that Craig Tufts passed away on June 21st.  Craig was Chief Naturalist at the National Wildlife Federation and made a huge impact in teaching us about gardening for wildlife and the joys we receive from restoring our backyard habitats.

He wrote two excellent books, The Backyard Naturalist, and The National Wildlife Federation’s Guide to Gardening for Wildlife, which continue to be wonderful resources.

Craig was a resident of Middleburg, and a member of Loudoun Wildlife Conservancy. In the early years of our Butterfly Count, he led teams and participated in the count – helping to grow our base of butterfly enthusiasts. He also participated in our Christmas Bird Count, including this past December in spite of undergoing brain surgery earlier in the year as he fought the cancer.

Craig was a wonderful resource for Loudoun and such an inspiration to all of us. We are thankful for all he shared with us and will miss him but will continue to hear his voice as we dig in the dirt, restoring Loudoun’s wildlife habitats and continue in his footsteps of teaching others about living with and appreciating wildlife.

His obituary can be read in the Washington Post.

On Saturday, June 27, we had our monthly bird walk at the Blue Ridge Center for Environmental Stewardship. Sponsored by the Loudoun Wildlife Conservancy and led by Joe Coleman, 5 warbler species were found, along with 36 other species.  Highlights were 2 singing Cerulean Warblers, Worm-eating Warbler, Ovenbird, Louisiana Waterthrush, and several Common Yellowthroats.  The Wormie came in to scold us, making us wonder if its nest was nearby.  We heard several Wood Thrushes and Scarlet Tanagers, catching glimpses of both, and heard just one Yellow-billed Cuckoo.  A Black Vulture emerged from one of the abandoned houses in the old settlement, where it likely has its nest.

Following is the complete list of birds seen:
Black Vulture, Turkey Vulture, Red-shouldered Hawk, Mourning Dove, Yellow-billed Cuckoo – 1, Ruby-throated Hummingbird watching us from a telephone wire, Red-bellied Woodpecker, Downy Woodpecker, No. Flicker, E. Wood-Pewee, Acadian Flycatcher – 4, E. Phoebe, Great Crested Flycatcher – 3, Red-eyed Vireo – 6, Blue Jay, Am. Crow, Tree Swallow, Car. Chickadee, Tufted Titmouse, White-breasted Nuthatch, Carolina Wren, House Wren, Blue-gray Gnatcatcher – 4, E. Bluebird, Wood Thrush – 6, Am. Robin, Eur. Starling, Cedar Waxwing – 5, Cerulean Warbler – 2, Worm-eating Warbler – 1, Ovenbird – 1, Louisiana Waterthrush – 1, Common Yellowthroat – 3, Scarlet Tanager – 3, Chipping Sparrow, Field Sparrow, Song Sparrow, No. Cardinal, Indigo Bunting, Com. Grackle, Am. Goldfinch

claude-moore-olive-hairstreak-jul-19-2008-111When going out butterfly watching, the key is to have binoculars that can give you good close focus.

Often when we go out on our butterfly walks, the individuals that we’re looking at are just a few feet away and while we may be able to identify them without using binoculars, when you do use them you can see so much amazing detail and color that the butterflies become that much more beautiful.

Some binoculars will focus as close as just 3 feet and this is excellent for butterflies but other excellent models will focus clearly to 5 or 6 feet and this works really well too.

In addition to looking at butterflies, close focus binoculars are great for looking at dragonflies and other insects as well as birds, wildflowers and mushrooms, among other things. There are so many incredible details in nature but we often don’t see because we aren’t focused in on them or are looking too quickly. Looking through binoculars can really help, both to slow us down and to give us the good views we need.

So I got home kind of late the other night (around 9pm) and as I turned into our street, I heard the loudest calls coming from our yard!

gray_tree_frog_1It was the Gray Tree Frogs that come to the little backyard pond we have set up.  Their chorus was amazing, drowning out all other night sounds by far.

As soon as I got in the house I grabbed my head lamp and camera and went back outside.

When the frogs are chorusing like this it’s incredibly easy to sit nearby and watch them (after you’ve figured out where they are). They are so intent on singing and defining territories and finding mates that even though I am only a few feet away from them they don’t seem concerned. (I also told them that I’m vegetarian and don’t eat frogs, so maybe that helps? ;) )

It’s sometimes hard to see the Gray Tree Frogs because they blend in to their surroundings pretty well. In many cases, they are actually in the brush around the pond rather than right in the water. When they move and splash a bit is when I try to hone in on their locations.

Something I noticed for the first time this night was that a number of the frogs were pairing up by the side of the pond rather than in the water where they would lay eggs. Upon inspection of the ponds this morning, I saw lots of egg masses. It will be fun to watch them hatch, grow and develop into froglets.

I’ve created a photo album on our Loudoun Wildlife Facebook page to share pictures from this big chorus night. It was really fun to go out and sit with them. At one point, as I was crouched next to the pond, getting “the shot”, I heard some splashing next to me.  There are Green Frogs in the pond right now too so I expected it to be one of them moving around but as I looked over, it was a raccoon washing it’s paws in the water. With all the frog commotion, it hadn’t noticed me, just as I hadn’t noticed it, and we both had looks of surprise when we spotted each other.

A fun wildlife night. I forgot to do a recording of the frogs that night but if they do it again in in the next day or so I’ll record them and post the audio file in the comments here or as a link off the facebook page.

In late July, I’ll be leading a night time field trip at the Blue Ridge Center to listen to and hopefully see Gray Tree Frogs. You can check our calendar for details. Space will be limited to just 15 participants and we can’t guarantee that the frogs will come out to play that night, but we sure hope they (and you) do.

binoculars_eye-reliefThe binocular makers have been working with this for ages so if you wear glasses but also want to use binoculars, not to worry. Many binoculars have either a rubber piece that folds up at the eye piece or the barrel of the eye piece rotates up, giving your eye distance from the glass of the eye piece itself.

The important piece of the puzzle to keep constant is the distance from your eyes to the eye pieces of the binoculars. So, when you select your binoculars, be sure to wear the same glasses that you would wear when you plan to use the binoculars. This will help you make sure that everything fits comfortably.

When checking the specs of the binoculars, check the “eye relief factor”. With wearing glasses, you want to have a long eye relief factor (e.g. 15-23 millimeters). If you have a short eye relief factor (e.g. a few millimeters), when wearing glasses, you will feel like you’re looking through a tunnel and this can give you eye strain and will reduce your field of view.
