Pair of pileated woodpeckers Neighborhood just east of Sligo Park, north of Dennis Avenue in Silver Spring 8pm, Mon, June 29, 2009 Laura Mol and Theo Meline Single pileated woodpeckers have been sighted before on this large silver maple in the backyards of Robin Road & Tenbrook Drive, up the sledding hill east of the basketball courts. This is the first time to see a pair: wow! Location is about 200 yards east of Sligo Creek itself.

Barred owl Near Harvey Road, West of Colesville Road Dusk, Thu, June 4, 2009 Stuart Armstrong It flew out of Sligo Creek Park and sat for about 45 minutes over a backyard pond which he watched closely. He also looked up a lot, since a Robin (who had a nest nearby) was dive bombing it.

Red fox Forty yards west of the trail, and about 50 yards south of University Boulevard. Sitting in the underbrush, just off the large clearing, staring directly out at the trail. 11am, Thu, June 4, 2009 Andre Williamson  
Bald Cypress trees and knees Left bank of Sligo Creek, a short distance upstream of Colesville Road Always Stuart Armstrong This is the northern most part of their range. There's a cypress swamp in Calvert County, about an hour away. But in general, you don't see many of these trees around. They prefer a milder climate.

Baltimore Oriole Tenbrook and Robin Roads just upstream from Dennis Ave Sun, May 31, 2009 Jed and Theo Meline The beautifully striking bird is easy to spot. Having seen it several times over the last two weeks, I hope that means it is nesting nearby. In six years living on the Creek and watching the birds somewhat closely, have never seen an Oriole before.

Red Fox Park Crest Drive near the park, north of Park Valley Rd, between Piney Branch and Maple 6:30am, Wed, May 20, 2009 Steve Metalitz Sauntering around in yards. Seen and briefly chased by a cat, then hurried off toward the creek.
Red Fox Pair Crossing the road and leaping through the high grasses near the stormwater pond just south of Forest Glen and the beltway 7:30am, Tue, May 19, 2009 Debra Benator Usually seen solo... first time to see a pair!
Yellow-Rumped Warbler, Warbling Vireo Takoma Branch - Poplar and Elm intersection - near Spring Park 10am, Sun, May 10, 2009 Mary Sue Fabulous - more warblers outside my window!
Black & White Warbler, Chestnut-sided Warbler, Redstart, Black crested Titmouse Takoma Branch - Poplar and Elm intersection - near Spring Park 10am, Fri, May 8, 2009 Mary Sue I opened the door to the balcony and waited --and all these birds showed out. A catbird came by to yell at me - I suspect a nest is nearby.
Red fox Ladd St. backing up to the headwaters of Sligo Creek 8:30am, Tue, Apr 28, 2009 Kathy Michels I surprised a red fox in our backyard just by the North west corner of my house. It hurried away towards sligo creek. Looked a bit ragged.

I stopped on the foot bridge and got a shot of the dam then saw the snake coming from the left crossing the creek. In the second shot the bulge in the body looks like the snake got some thing to eat. I would guesstamate it might be around 5' to 7' long.

Woodchuck (Groundhog) On two occasions by the James/Mary Lee Chestnut Ridge bench just south of University Blvd April 2009 Stuart Armstrong It has a den up the hill at the edge of the woods but grazes in the grass.
Yellow-crowned Night-Herons, 2nd nesting pair At the south end of the parking lot near Dallas Ave, in a large tree just north of the bridge 2:30pm, Sun, Apr 19, 2009 Trish Koch I went to look at the first pair, just over the parking lot. One was deep in that nest. While looking around I found the second pair, about 50 feet south.
Yellow-crowned Night Herons - two on a nest Nest is on the south/west side of Sligo Creek Parkway, high in a tree over the small parking lot near Dallas Ave. just downstream from the golf course. 6:40om, Thu, Apr 16, 2009 Trish Koch  
3 Yellow-crowned Night Herons, Mallard Ducks and small fish The Ducks were at Piney Branch Rd.

Yellow-crowned Night Herons and Nest High on a tree limb over Sligo Creek just downstream from Piney Branch Rd 3pm, Sun, Apr 5, 2009 Don Olson A group of folks had gathered around trying to see what the birds were. The one on the nest seemed to be working on the nest or tending to something in the nest. One of the ladies said that she heard what she thought were small bird sounds coming from the nest, I must admit that I did not hear any thing. To be honest I do not know that I have ever heard any Heron make a sound.

Pileated Woodpecker and lots of new mayapple Lower Long Branch, between Carroll Ave. and the Jackson St. bridge Thu, Apr 2, 2009 Michael Wilpers This was the first pileated woodpecker I've seen in Long Branch. The profusion of mayapples was encouraging, as they have fought their way up between leaves of English ivy that carpet the ground to claim their rightful place in the sun.

Wood frog, American toad, deer bones, & dozens of skunk cabbage leafing out Kemp Mill area. Vernal pool and along hiker-biker trail 10:30pm, Sat, Mar 28, 2009, 10:30 p.m. Michael Wilpers The wood frog sat motionless on a stick protruding from the vernal pool the entire time I was there (looking in the pool and under rotting logs for salamanders). The deer bones were hidden beneath the leaf-litter nearby. The tiny American toad was sitting in the mud by the hiker-biker trail directly east of there. The skunk cabbages were coming up all along two gulleys a bit downstream and to the east of the trail.

Great Blue Heron About midway between Maple Ave. and the Carroll Ave. Bridge 2pm, Fri Mar 27, 2009 Don Olson Walking upstream from the Carroll Ave. Bridge I saw the Heron fishing from the rocks and it was kind enough to let me take a few shots from the path (note the mating plummage on the back of the head).

One Mourning Cloak butterfly, five Wood Ducks, and six or seven turtles Wood Ducks and turtles at the Kemp Mill stormwater ponds; mourning cload along the hiker-biker path just upstream from where the path splits. 3-5pm, Sun, Mar 22, 2009 Michael Wilpers Three male and two female wood ducks flew down from upstream on to the western pond. After paddling around for 15 minutes, they camped out on the western bank. The turtles were basking on logs and the bank on the north side of the eastern pond. Tentative ID (by Jo Arnone) is that these are Red-Eared Sliders, a mid-western & southern species introduced across central Maryland, probably by pet owners or science students.

Wood Frog egg mass Vernal pool in Kemp Mill 11:45pm, Sat, Mar 14, 2009 Michael Wilpers Eight adults and one teenager went looking for breeding salamanders after a day of drizzle. Didn't see them, but found this fresh batch of wood frog eggs. They'll hatch in a couple weeks. If the pool doesn't dry out, the tadpoles will live there for a couple months before turning into adult wood frogs and heading back into the woods.

Daphnia (a tiny crustacean) In one of the vernal pools along Wheaton Branch, downstream from Woodman 11:45pm, Sat, Mar 14, 2009 Michael Wilpers These minute critters (also called "water fleas") were swarming in tremendous numbers and seemed to be attracted to our flashlights. They play an important role in vernal pools by breaking down leaf litter and providing abundant food supply to larger organisms. Enlarged image taken through a field microscope at home.

Spring beauty petals below duff Twelve-Acre Wood, upland slope, north of Dennis Ave Sat, Mar 14, 2009 Laura Mol Pulling Japanese honeysuckle, I saw the oak-leaf duff lift to reveal the yet unfurled pink-white petals of the Spring Beauty (a lovely, small wildflower)on two plants. The linear leaves of scores of other Beauties were clearly visible all across the east-facing slope. Early garlic-mustard leaves are also showing; the young and ofter long root system pulls out entire--at least from the moist, soft woodland soil of this part of Sligo Woods
Large owl (probably Barred Owl) About 100 yards downstream from University Blvd 11:30pm, Sat, Mar 14, 2009 Michael Wilpers It was standing motionless on the west side of the road, looking more like a statue of an owl than a live bird. It stayed put as I passed, looking like a hitch-hiker, and then as the car behind passed, finally taking flight only as the third car went by (all driving south). Tentative ID by Helen Gray, who was in the second car, with help from Gary Lear, who was in the third car (part of our Salamander Search group).
Eastern Screech Owl Near Long Branch, between Carroll and Maplewood Avenues 9:30pm, Thu, Mar 12, 2009 Michael Wilpers Perhaps the same owl I've heard the last few years. I've only noticed it singing the low tremolo song (which functions as the pair and family-contact song), never the high whinny (its territorial defense song). An inspiring regular feature of my neighborhood.

Barred owl In the woods by Sligo Creek, about 1/4 mile south (downstream) from University Blvd Thu, Mar 12, 2009 Stuart Armstrong Larger than a crow but stocky and square, with a short tail. Dim light but clearly saw silhouette, rounded head and a little detail on throat. Did not have a light face, and had no "horns". I walked to University Blvd. On the way back I heard it hoot (after dark). I had heard an owl hooting along Sligo Creek earlier this year as well, and thought that it was a barred owl.

Great Horned Owl - male & female Perched in trees by Park Valley Road bridge (section 3), then moved to trees slightly downstream, and then flew off to the west dawn, Sat, Feb 21, 2009 Audrey McMorrow I first heard the Bubos (Great Horned Owl = Bubo virginianus) about a week before, around 5am as I entered the trail from Wabash. I had been calling to them each morning since (although my call leaves a bit to be desired). I was DELIGHTED to subsequently have them fly overhead and then perch at Park Valley Bridge - then move two more times allowing me excellent views.

Mourning Cloak butterfly & unidentified hawk Dowstream from NH Ave. The mourning cloak was flying above the paved path that connects Drexel St with the hiker-biker trail. The hawk was perched in a tree along the west edge of the powerline corridor. Mon, Mar 9, 2009 Michael Wilpers The mourning cloaks are the longest-living adults of all eastern butterflies, hatching in summer, semi-hibernating in fall and winter, re-emerging on warm winter days and then in spring to mate. The hawk was being mobbed by blue jays and flew off before I could get a good look at it.

Hooded Merganser (pair); Wood Ducks (3 pairs) University Blvd stormwater pond 10:30 am, Mon, Mar 9, 2009 Leah Haygood Very good look at a pair of Hooded Mergansers. I've never seen them in Sligo before. I assume they're passing through. I hope the Wood Ducks stay and nest. Also a couple of pairs of Mallards -- they've been there all winter. The Great Blue Heron who wintered there has left. A pair of Red-Shouldered Hawks have been screeching at each other -- nesting nearby?

Red-tailed hawks on nest Deer path south of Colt Terrace field, visible from the bike path about 100 yards south of Orebaugh Ave 10:45 am, Mon, Mar 9, 2009 Leah Haygood I have been seeing and hearing them in the area recently. Saw both on the nest. The nest is kind of small for such a big bird -- looks a lot like a squirrel's nest.
Great Blue Heron In the creek, just downstream from the second foot bridge crossing the creek (coming from Colesville Road, heading towards Wayne Avenue) 9am, Fri, Mar6, 2009 Jim Stedman Seeing a heron in the creek led me to slap the Yellow-crowned Night-heron label on it, an absurd misidentification I shared with several folks on the path. My apologies. Clearly, it was a Great Blue -- the web picture posted here and my Sibley Guide make that clear.

Muskrat A pond upstream from Forest Glen Rd 3pm, Tue, Feb 17, 2009 Don Olson I was standing on the bank of the pond when I saw some thing swimming from the far end of the pond toward the center. As I watched it came to some ice in the center of the pond and dived down and I never saw it again.

Many species of grasses in winter stalks Within the unmown portion of the Pepco corridor, on either side of the creek, between NH Ave. and East-West Highway Mon, Feb 16, 2009 Michael Wilpers A gorgeous palette of textures and shades of winter color, as the ROW hasn't been mown for more than a year. Considerable amounts of broom-sedge (Andropogon virginicus), purple-top (Tidens flavus), and poverty grass (Danthonia spicata), somewhat less Indian grass (Sorghastrum nutans) and bentgrass (Agrostis perennans), as well as little bluestem (Andropogon scoparius), deer tongue (Dichanthelium clandestinum), flat-stemmed panic grass (Panicum anceps), purple love-grass (Eragrostis spectabilis), and nimblewill (Muhlengergia schreberi). IDs by Randy Pheobus, who led M. Wilpers, L. Mol, and B. Sidwell in a survey of the ROW.

Red-tailed hawk At the downstream border of the Pepco corridor, about 40 feet up on a tree limb, being harassed by several crows Mon, Feb 9, 2009 Michael Wilpers It outlasted the crows, who departed. A few minutes later, the hawk took flight, crossed over the powerline corridor, and alighted on a branch high in a tree on the opposite edge of the ROW. I'd like to think that the unmown corridor has provided an improved source of prey for hawks and owls and will lead to further sightings.

Red Fox - a teenager Crossing Poplar, going away from Spring Park in Takoma Park 8:30pm, Thu, Jan 15, 2009 Mary Sue I saw the small red fox cross the road. I saw a Big Red Fox cross the same road about the same time 8 weeks earlier. I suspect a den is close by.
