Some Birds, Mostly Herps of Lincoln County, CO – SOLD OUT

Leader, John Vanderpoel
Fee: $125
Limited to 8

Monies raised from Interludes with Nature trips, provide the opportunity for Colorado teens, including our Teen Naturalists, to attend nature camps in Maine or the Colorado Rockies.

Registration: Registration information here.

Lincoln County is incredibly rich in reptiles with 11 species of snakes, including 2 kinds of rattlers, 2 species of skinks, Painted Turtles and 4 types of lizards, most notably the Short-horned, a species of special concern. October is the month when snakes heading to their winter hibernacula become easier to spot along dirt roads in eastern Colorado.

We will leave from Boulder on Saturday morning, and in early afternoon, visit a private ranch north of Limon to look for reptiles and birds. During this late migration period, we are likely to find raptors, sapsuckers, lingering warblers and wintering sparrows. After breakfast on Sunday morning, we head east to work the gravel roads for migrating snakes and reptiles. We will drive home later in the afternoon..

Although John is best known as an elite birder, he is passionate about herpetology and makes several trips a year searching out various species in their preferred Colorado habitats.

You are responsible for the cost of your night in the hotel as well as all meals. Most of Limon’s hotels serve breakfast and it won’t be necessary to start early on Sunday. BCAS will provide snacks and soft drinks. We expect all participants to listen carefully and obey all directions from John concerning approaching any snakes. You will risk a “time out” if we feel that you are endangering yourself or others!

Fee: $50
Limited to 15

 Monies raised from Interludes with Nature trips, provide the opportunity for Colorado teens, including our Teen Naturalists, to attend nature camps in Maine or the Colorado Rockies.

Registration: Registration information here.

Mid-May is a sweet spot for witnessing the widest variety of migratory birds in Boulder County. Join one of this area’s most accomplished young birders, Luke Pheneger, for a big day adventure in this rich and varied habitat. About 100 species should be attained with the expected mix of ducks, geese, shorebirds, herons, egrets, hummers, woodpeckers and songbirds, including warblers and sparrows. The Sawhill and Walden conservation areas are surrounded by Boulder Creek and include marshes, ponds, meadows and woods. Many rarities have been reported over the years and with Luke’s exceptional eyes and ears, you might well expect some pleasant surprises.

After a full morning of birding, bring a folding chair, take your picnic lunch break and do a Big Sit for a while, while all scan the skies and marshes for more species. Then, it’s back for another loop around the complex to see what has arrived. BCAS will provide soft drinks and treats. Be prepared to walk 2-3 miles and bring a picnic lunch, binos (please ask if you’d like to loan a pair), scopes, cameras and the usual outdoor gear.

Marvelous Moths of Boulder County with Pam Piombino

Friday, July 24, 2020

7:45 p.m. – 11:00 p.m.

No cost, limited to 8, RSVP to Pam Piombino

Leaders: Pam Piombino, piombino.pam@gmail.com

 

Please join Pam Piombino for an evening introduction to the “night butterflies” of Boulder County, CO. Why moths? They are major and undervalued pollinators, they are major food sources for bats, birds, mammals (including bears!), reptiles, spiders and other insects. They are often as beautiful as their day-flying cousins or incredibly cryptic. There are tens of thousands of species, making them one of the most diverse life forms on the planet.

This evening is timed to be part of an annual event, National Moth Week, during which citizen scientists from around the world put out special lights to lure moths to white sheets. Our findings will be shared with major online biological databases. You will help document diversity, seasonality, distribution and variability. Please no pets, no nets.

Where to Meet: Details will be provided to those who RSVP.

Banding Baby Barn Owls (2 spaces open)

Banding Baby Barn Owls (2 spaces open)

Leader: Scott Rashid
Date: Early evening, last third of June, 2020, depending on the birds
Location: TBD
Limited to 12 people
Fee: $50.00

Monies raised from Interludes with Nature trips, provide the opportunity for Colorado teens, including our Teen Naturalists, to attend nature camps in Maine or the Colorado Rockies.

Registration: Registration information here.

Back by popular demand: In 2014, Scott Rashid, of the Center for Avian Research and Rehabilitation Institute, (CARRI), embarked on an experiment. Would there be more Barn Owls in Boulder County if there were more breeding cavities? With grants from Boulder County Audubon and others, Scott began installing nest boxes on private properties in northern Boulder County. Since then, dozens of baby Barn Owls have fledged and been banded. Thousands of people have addictively watched one of his live web cams to follow the fascinating processes of courtship, breeding, brooding, hatching and the feeding of these enigmatic birds.

Join us early one evening to watch Scott band the nestlings from one of these sites on private property. Scott will talk about the biology of this very special species and the amazing places in which some of his bands have been recovered. You will have charming photo ops and perhaps the opportunity to even hold one of the young.

Scott is an artist as well as a licensed bander and rehabilitator. He has authored and illustrated the following books, all of which are available through him: Small Mountain Owls, The Great Horned Owl, an In-Depth Study and Northern Goshawk, The Gray Ghost. His newest, published in October of 2019: Exploring The World Of The Barn Owl.

Shorebirds in the Grass with Steve Jones

Shorebirds in the Grass with Steve Jones

Join longtime Boulder Audubon member and former president Steve Jones to learn about the shorebirds in the grasslands on Tuesday, May 26th 2020.  In addition, to the fascinating talk by Steve, this meeting will include the BCAS Board elections and the presentation of our annual awards.  To nominate yourself or someone else, please write crossbill@boulderaudubon.org by 15 April 2020.

It seems strange but more than a dozen familiar shore and wading birds don’t nest by the ocean at all. These “upland” shorebirds and waders lay their eggs in the soft grasses of some of our most verdant prairies, or sometimes on bare sand flanked by tufts of grass. Though the presentation, we’ll journey to the Nebraska Sandhills to explore the lives of Piping Plovers, Long-billed Curlews, Marbled Godwits, Willets, Upland Sandpipers, Black-necked Stilts, White-faced Ibis, and many more. Along the way, we will explore why so many of these species are thriving in this oasis on the Western Plains.

Steve Jones is author of The Last Prairie, a Sandhills Journal, and co-author of The Shortgrass Prairie, the Peterson Field Guide to the North American Prairie, Colorado Nature Almanac, Wild Boulder County, and Butterflies of the Colorado Front Range. Steve organized the first comprehensive small owl and wintering raptor surveys in Boulder County. He helped organize and carry out the first and second Colorado Breeding Bird Atlas projects. His 28 years of consulting work includes more than three-dozen breeding bird and resource inventories for city, county, and state open space programs. He taught in the Boulder Valley Public Schools for 33 years, and he is a past president of both the Boulder County Audubon Society and Boulder County Nature Association.
