Directions:Meet at parking strip on north side of Ferril Lake. Enter park from Colorado Blvd. Northbound turns left onto 22nd Ave. past Museum of Nature & Science; southbound turns right onto 22nd at police station. Go past museum parking until road curves toward zoo. Take immediate left at "To Pavilion Bandstand" sign and go 300 yards down to corner with tall spruce trees, where lake comes into view. Park diagonally on left beneath spruces. We'll check on the cormorant and egret colonies but focus on early autumn migrants. The last day of September (and our DFO Big Month) is on the cusp for returning waterfowl and winter residents, migrant warblers and other southbounders. We'll walk 2-3 miles, from Ferrill Lake to the "pinetum" below the Denver Museum of Nature and Science and back west to Duck Lake and productive old groves on the park's west side. Dress for the weather and bring water and snacks. Register online or contact leader. *9 people have registered for this trip. There are 5 spaces available.* *Guanella Pass* 7:30 AM - 5 PM Chuck Hundertmark & Paul Slingsby ( chundertmark8ATgmail.com or 303-604-0531, paslingsbyATcomcast.net or 303-422-3728) Trail Difficulty: Strenuous Directions: We will be exploring stops along the road between Grant and the top of Guanella Pass. We will depart from the Twin Forks Park-n-Ride, 6164 US Hwy 285. Going south on US 285, the Park-n-Ride is on the left just past S. Turkey Creek Rd. Details: We will encounter a variety of habitats including coniferous forests, mixed forest, willow carr, subalpine and alpine regions. We may take short walks up to 2-4 miles at high altitude. Bring water, snacks, lunch, sunscreen, insect repellent, and clothing layers. Wear sturdy shoes. We will be looking for sparrows, flycatchers, woodpeckers, and perhaps the elusive ptarmigan. Register online or contact leader. *There are 12 spaces available for this trip* *First Creek at RM Arsena*l October 1, 7:00 AM - 12: PM, John Breitsch (jbreitschAThotmail.com or 303-588-0552), Trail difficulty: Easy, Maximum participants: 15. Directions: From East Denver take 56th Ave east toward Pena Blvd. First Creek parking lot is just before Pena on your left (north). Or take I-70 east to Pena Blvd. Drive north to 56th Ave Exit. Turn left at the light and at the bottom of the off ramp, pass under the highway and turn right, almost immediately, into the First Creek parking lot. We will start at the same parking lot as 1st Creek @ DOS. We will walk up Buckley Road, then we turn west at the creek instead of east. The trail should be finished all the way out to the concrete bunker that can be used as a viewing blind. We'll hope to see some late migrants and a few resident species. Until recently, this was a part of the RM Arsenal that was inaccessible. It should make for great raptor viewing over the winter months. There currently are no restroom facilities. *There are 10 people registered for this trip. There are 5 spaces left* *For more information on the field trips go to* dfobirds.org.
