Christmas Bird Count excel template

 

CBC compilers: Would you like an excel template for compiling your CBC?

Just ask.

I have been compiling two or three CBCs for many years. They are small counts of four areas each with 12-20 field counters and half a dozen feeder watchers. 32-52 species.  Field Tallies are got to me by eBird trip reports (more on that in the autumn) and feeder watchers report by email usually.

This is what I use. It has no macros or complicated formulae.  There is only one cell reference to another sheet.  If you know a little bit beyond basic excel, you can add areas and feeder watchers fairly easily.  If you would prefer I adapt it for you, I maybe able to (I know only as much excel as you see here), for a small donation to the Rocky Mountain Naturalists - tax receipt available.

Features:

  • Subtotals for field and feeder watchers
  • Count of countable taxon
  • Count week species separate
  • Weather Audubon style
  • Effort calculator for multiple parties
  • Effort data entry adaptable to be done by area leader
  • etc

July Meeting, What a Venue!

Submitted by D. Calder

With the generous permission of a Wycliffe land owner, naturalists were able to visit a small pothole lake situated in the heart of rolling grasslands one mid-July evening.

A variety of habitats including multi-colored alfalfa, native grasses, scattered clumps of trees and brush, and muddy shoreline surrounded the open water. A couple of yellow pine snags provided nesting cavities, and perches for the Osprey and hawks. As the evening winds subsided, a greater assortment of waterfowl could be identified, some trailing strings of ducklings across the calmer water.

A few wildflowers dotted a rocky meadow where sharp eyed naturalists noticed an uncommon, singular, mauve flower. To quote from the 1952 book “Trees, Shrubs and Flowers to know in British Columbia”, by C.P. (Chess) Lyons, “The simplicity of this beautiful flower imparts an air of rarity that is further enhanced by it’s random appearance in drab range land. The stout stem carries one or more pale purple or lavender blooms often 2” across. Three large petals are marked on the inside with dark blotches near their base and a green band down their centre. One thin leaf grows from the base of the stem. The Sagebrush Mariposa Lily is seldom found in any quantity and often escapes notice because of it’s delicate shading...” Thanks, Chess. (1915- 1998)

As the evening light ebbed and the reflected sunset intensified, a couple of us heard the unmistakable call, a series of 3 to 8 deep, soft ‘hoo’ notes, of the Great Horned Owl.

Conveniently, it perched on a nearby fencepost.

This large, heavy-bodied owl with noticeable ear tufts has glowing orange or yellow eyes on a tawny-brown facial disc. It is one of the largest owls in the Rockies and has ear tufts or horns which are toward the sides of the head. The eyeball of the great horned is as large as a human eye, and like other owls it has binocular vision. Its’ ear openings are of unequal size which also helps it to locate prey. The finely toothed edges of the outer primary feathers allow almost noiseless flights by this large predator. Along with long, sharp talons, these special adaptations make this mostly nocturnal owl an extremely effective predator on small rodents, birds, hares and even skunks.

As is the general case with owls, the female is considerably larger than the male, although the male has a deeper voice. They are year-round residents in the Rockies and very early nesters, sometimes incubating eggs beneath a blanket of snow. In February and March, naturalists make night time outings to detect the owls as they call to each other while establishing territory and preparing to breed. Submitted by Daryl Calder.

2012 Crocus Walk

The object of our affections





This year's "Crocus Walk" by the Rocky Mountain Naturalists was held on 21 April 2012 and a lovely day it was.

We take a short leisurely hike up onto the bench behind Wasa Lake Provincial Park Campground looking for various plants and birds, hoping we have timed the field trip for when the Mountain Avens are in bloom. We were pleased to have done so.

Pardon me for not keeping a list of plants but I do remember the words antenaria and macrocaudus, nodding onion and moss campion. But my favorite since childhood is the Mountain Avens as above.

This field trip, and the one previous, are held in honour and to reminisce about two of our long-time members who have passed on, Anne Redfearn and Mildred White, whom every year faithfully searched for the first buttercups and crocuses.  They were also active birders and contributors to the Birds of British Columbia, and Mildred's historical records have been transcribed onto eBird.



After the walk at Wasa, we returned to 'Mildred's Meadow' where the previous field trip had been, to check on the flowering progress of the Buttercups. Many were now out in full bloom - and the patch seems to be spreading between the pines.

Then we went in search of interesting birds and were rewarded with the now regularly-found EURASIAN COLLARED-DOVE, whom appear to be nesting in a residential area of Wasa, and two of our favorite species, the SANDHILL CRANE, of which we saw four striding through the marsh at Bummer's Flats, and the BLACK-BACKED WOODPECKER in a recent burn.
