All posts for the month December, 2011

After posting the blog about insects in my backyard habitat I was asked several questions about my yard. Every season has color, interest, and surprises for me which I will share over the next several months.

Nocturnal scene in my neighborhood of Thornberry.

Daytime in Thornberry: A sweep of winterberry holly berries add color from the street with the Southern Gentleman (male of this species) being tucked into the back of the garden.  The male produces no berries, but is necessary for the female to produce hers.

Winterberry add color to the winter garden and is a native plant found in wet woods. Many species of birds, including Eastern Bluebird and American Robin feed on the berries.

Over the next few months the birds will enjoy the bounty of berries. It depends on which species you plant whether or not the birds devour the berries early or late in the season. For some interesting texture in the winter garden, try River Birch, whos peeling bark adds interest to the leafless tree and nooks and crannies for overwintering insects and spiders. 

River Birch is another native Delaware Species that is found in wet woods and streamsides, especially on the coastal plain.

Final post in a 4-part series about the Delaware Nature Society trip to Costa Rica in November, 2011.

We finally made it to the west coast of Costa Rica.  After a long day in the bus, we were rewarded with a gorgeous beach, new wildlife and looked forward to a few more days in this green and wonderful country.  With the Pacific Ocean in view, we stayed at Punta Leona, a quiet beach resort which is smack in the middle of the best place in the country for a very rare bird…Scarlet Macaw.  The simultaneous sounds of waves crashing and macaws screeching as they winged by will not be forgotten soon. 

Manuel Antonio National Park was a day-trip while we stayed here.  Picture a mountainous tropical forest flanked by sand and rock beaches with clear blue water.  On the beach, White-faced Capuchin monkeys walk right by, looking for a forgotten sandwiches left behind.  These monkeys have no fear of humans here, as you will see in the video below.  We stood within 5 feet of some of them, resulting of some pretty scary face to face monkey photographs.

Finally, check out the end of the video which features the highlights of our crocodile boat tour where we saw many birds, and a crocodile breakfast.  I am not a big fan of feeding wildlife for show, but I must say, my tip for the boat tour operator went up drastically after watching his dangerous skill.  I still have wonderful dreams and memories of our trip to Costa Rica with Collette Vacations.  Come join the Delaware Nature Society on a trip someday…you won’t regret it.  Enjoy the video, and check out the complete list of wildlife seen on the trip below.

Third post in a series about the Delaware Nature Society Costa Rica Trip in November, 2011.

Arenal Volcano looms above the surrounding forest and farmland. Photo by Joe Sebastiani

For the 24 hours before it erupted, the ground shook violently and cows stopped drinking because the cool spring water had turned hot.  On July 29, 1968, Arenal released its energy with huge explosions and lava flows, filling the sky with ash and hurling rocks the size of cars 5 km away.  Toxic volcanic gas settled into surrounding valleys…80 people and 45,000 cattle were killed, and 3 towns were destroyed. 

On our visit to Arenal with Collette Vacations, the volcano did little more than emit a little steam at the top, but its perfect conical shape and black rock sides were a beautiful sight.  We spent three nights here at the luxurious Arenal Springs Resort, where the volcano sets a magnificent backdrop from your doorstep as well as the hot-spring fed pool with a swim-up bar. 

One of the rarest birds on our trip was the Keel-billed Motmot we found while touring a dairy farm near Arenal. Photo by Marilyn Henry

With Arenal in the background, we continued our nature excursions, birding everywhere we went.  The landscape in this area is beautiful.  Forest-covered hills, the volcano, and lots of farms in the lowlands.  While touring a dairy farm and learning the art of Costa Rican cheese making, we spotted one of the rarest birds on the trip, a Keel-billed Motmot.  With a spotty distribution in Central America, and considered a rarity in Costa Rica, and we were lucky to stumble upon it.

The other Keel-billed creature we found in the area was a beautiful Keel-billed Toucan. A rainstorm approached behind it, and when it called, it sounded like a chirping frog. Photo by Joe Sebastiani

Our guide, Jose Saenz, warned us about Monteverde.  “Bad does not describe the condition of the road from Arenal to Monteverde.  It is going to take all day, and we might not make it.”  Despite these dire predictions, when Jose asked for hands to see who still wanted to make the trip, all but one went up.  Into our bus we went at 5:30 a.m then next morning.  We boarded a boat to cross Lake Arenal at 6:15 a.m.  Into an0ther smaller bus and a 4-wheel drive vehicle we scrunched at 7:00 a.m.  Up the muddy, potholed jeep track we meandered slowly until 7:30 a.m. when the small bus got stuck.  Out of the vehicles we climbed.  Good thing we had the 4-wheel drive vehicle to pull the bus up a steep slope and out of trouble…not once, but twice.  Out and in, out and in.  Standing on a foggy mountainside, watching the bus being pulled out of trouble someone said, “And we are doing this because…??”  When we got to Monteverde at 9:30 a.m. we found out.

The dripping, foggy, moss-covered forests at Monteverde made us forget about the cramped, long drive to get there. Photo by Joe Sebastiani

For the next 4 hours, we lost all sense of time in the Monteverde Cloud Forest.  Crossing canopy walkways, being swarmed by 100 hummingbirds of 7 species at a feeding station, finding new birds, butterflies, and orchids and soaking up the pure beauty of this world-class location made us forget all about the crazy ride up the mountain.

A Coppery-headed Emerald and six other species of hummingbird swarmed the feeders here. There were probably 100 hummingbirds all around us zipping around, fighting, feeding, and nearly touching us. Photo by Joe Sebastiani

We couldn’t tear ourselves away from the incredible hummingbird feeder station here.  Coppery-headed Emeralds, Violet Sabrewings, Green-crowned Brilliants, Green Violet-ears, Stripe-tailed Hummingbirds, Purple-throated Mountain Gems, and Magenta-throated Woodstars formed a buzzing cloud around us.

We slowly walked the path at Monteverde and lingered on long canopy walkwaybridges in the treetops.  Migrant Broad-winged Hawks, which nest in eastern North America circled overhead and reminded me of the connection the tropics have with forests at home.  A Black-throated Green Warbler, another North American migrant, fed in the trees with a Spangle-cheeked Tanager, assuring me I was still in the great mountain forests of Central America.  Where to next?  The coast of the Pacific Ocean…stay tuned!

A lasting memory for all of us on the trip to Costa Rica will be walking just under the clouds on the canopy bridges in Monteverde. Photo by Joe Sebastiani

This amazing photo of an immature Golden Eagle was taken by Hawk Watch volunteer Kim Steininger in November as it flew past Ashland Hawk Watch.

Ashland Hawk Watch, in its 5th autumn, began on September 1 this year.  As of the end of November, it has proven to be one of the best years yet, with 13,548 raptors counted…so far.  Cyrus Moqtaderi, in his third year as the Hawk Watch Coordinator, is staying on to count a bit more in December.  We couldn’t be happier!  Migration is continuing, and we expect to see more Red-tailed and Red-shouldered Hawks, and possibly more Golden and Bald Eagles, and perhaps a few surprises.  The Hawk Watch will be operating sporadically over the next few weeks, usually on days fit for raptor migration.  Cyrus will announce when the Watch will be open the day prior on the de-birds list-serve.  If you don’t subscribe to this e-mail list-serve, you can look up posts here.  Just sort the posts by date and pick the latest post from Cyrus.

Here are the numbers for the season through November:

Black Vulture – 742

Turkey Vulture – 1,621

Osprey – 469

Bald Eagle – 306

Northern Harrier – 144

Sharp-shinned Hawk – 3,169

Cooper’s Hawk – 538

Northern Goshawk – 4

Red-shouldered Hawk – 375

Broad-winged Hawk – 4,455

Red-tailed Hawk – 806

Golden Eagle – 11

American Kestrel – 680

Merlin – 80

Peregrine Falcon – 27

Short-eared Owl – 1

The Ashland Hawk Watch is a joint project between the Delaware Nature Society, Delmarva Ornithological Society, and the Delaware Division of Fish and Wildlife
