Field Guides

Many people come to the store asking us what the best field guide is, and I really find that it varies from person to person. I personally love Sibley's while other may prefer Petersons. In this post I hope to give some good pro's and cons of each of the most popular field guides. I also tend to recommend different guides for different levels of knowledge. For instance those that come having never noticed a bird in their life but are interested in starting I will recommend a guide that has photos, but mention that as they get farther along they should come back and consider a Sibley's or Petersons. Photo guides are (sometimes) more simple than say Sibley's where there are 6 different drawings for one individual bird.

 I'll start with the two that have hand drawn illustrations.

Sibley
Pros
I love the Sibley guide for a number of reasons but mainly its the amazing illustrations and the variation he captures in different individual birds. He draws multiple plates for each bird flight from above, flight from bellow and perched. He gives details on habitat, voice and behavior. He draws and point out difference between males and females as well and similarities between species. At the beginning of each section he has a page with all the female or juvenile birds of that section. This way you can glance at that page and narrow it down by comparing all the field marks to similar species and then jump directly to that species page. I have found this especially useful for the warblers and the Calidris sandpipers. The second edition of the Sibley guide came out less than a week ago and I have read very mixed reviews about it. Mostly that the drawings are printed too darkly, but it seems some like it and other don't. We'll see.

Cons
Range maps in the Sibley guide are terrible. I can hardly see them and where the cut off are. I don't recommend solely using the range maps in any guide. None are accurate enough as ranges tend to fluctuate. I prefer places like ebird to find more accurate range maps, but there is no range map that is 100% accurate.


Petersons
The Peterson guide was my first illustrate field guide and I used it for quite some time before I was gifted the Western Sibley. The illustrations in Peterson are very beautiful but sometimes lack the life-like aspect that Sibley gives us. I find some of the birds to be somewhat disproportioned and there are much fewer examples of each species. I was misled for years about the identification of the Empidonax flycatchers because of the extreme variation he draws between species, but he also draws them over their specific habitat which, when I discovered exactly how similar they do look, to be very useful, he also has simple little lines that visualize the calls of the flycatchers which I have also found very useful.


And now for photographic guides.

Stokes
Stokes was the first guide I ever bought and I loved it until both front and back covers had torn off. It has good photos and each page is consistent with is organization, photos at the top text at the bottom. Unlike the other guides which are a little more helter-skelter with drawings sorta spread about and grouped with similar species for comparison etc. The stokes is great for a beginner whose main focus is to identify the bird at hand and not compare it to its regional subspecies or strange variants that may exist elsewhere.

Crossley
I love the Crossley guide for its strange page layout. It has close ups of each bird at the front of the page in different positions and then as they go back they get smaller and they are positioned in a large variety of ways. All the photos are cut out and places very nicely over a natural photo background. It really helps give a good comparison of all angles and variations. Its sort of surreal looking at a photograph with 20+ Brown Pelicans all in some strange position. I find this book especially useful for identifying gulls because it has so many photos of each one. Especially in tandem with sibley.

The downsides on this one is its size. Its is very large and doesn't make a very good field guide. I use it mainly has a reference book when I return from a trip.
Also only and eastern guide is available!

Kaufman
To be honest I've never really used Kaufmans because I've always been very turned off to it by its strange Peterson-like placement of photos on the right page and text on the right. This has always been annoying to me because it is sometimes difficult to correspond the right bird to the correct text when there are say 8 birds on one page and a solid page of text on the other.
That being said each bird is well represented in terms of information and photographs. Important field marks are pointed out and the photos are clear, focused and generally well lit. This isn't a bad book in any sense and I would trust it and use it in the field.

I think all these books are useful to have on a bookshelf and I strongly believe that they can all be used in tandem to help expand ones knowledge of habitat, behavior, and field and identification.
And if not it is an excuse to buy another book!

*Disclaimer-these are all my personal views and thoughts. You are all welcome to your own.

Landowners and Conservation


For my English class I wrote an essay about the cooperation between biologists and landowners when it comes to conservation. Below is sort of a summary of the essay.
 
 
Burrowing Owl
 
     Conservation is very important for the future of humans and the well being of the planet. Often times conservation becomes an argument between biologist and landowners, but it doesn't have to be. There are many organizations who have created partnerships with landowners, helping them understand that conservation doesn't mean a loss of profit. These organization offer incentive based programs for landowners that encourage them to practice good grazing techniques and keep portions of their property true to native habitats.

Hudson Gardens 9-14-2013




Todays hike at Hudson Gardens was a great success! We had a large flock of mixed sparrows about a fourth of the way into the walk and no matter how hard we tried we couldn't get a great view of all them. They were constantly flitting up and down and left and right and back and fourth. The good looks we did get turned up several Song Sparrows, a few Vesper Sparrows, a Lincoln's Sparrow and the most exciting a Clay-colored Sparrow! Several other species went unidentified because of brief glimpses. One we thought perhaps was a Field Sparrow because it showed some rusty red on its head, a grey nape, as well as a strong eyering, no one ever got a good enough look however so it is going uncalled.






We also had another great opportunity of observe Mallard in their eclipse plumage. Now why look at Mallards you say? If you know the common birds like the back of your hand your less likely to misidentify them as something else when they change into winter or non-breeding plumage.
Male Mallards in eclipse plumage look a lot like the females but pay attention to the color of the beak and the feet and also the males will have a much darker breast than the females but often without a female right next to the male it can be hard to tell the difference. Remember female Mallards match, they have a orange (and black) beak and orange feet. While male Mallards don't match they have a yellow beak and orange feet.





We stopped at the Songbird Gardens and watched several Black-capped Chickadees, American Goldfinches and House Finches feed and chase each other around. As we made our way back to the gift shop we walked through the pine forest and enjoyed the scent of the various conifers. We passed a few very vocal Black-billed Magpies and came upon a lovely butterfly bush surrounded by butterflies. There was a Painted Lady, a Monarch and Fritillary Sp. all feeding at the same time.

Birds Parts, Terms and Uses.


 
Buffy malars, no primary projection, white supercillium? these are all terms heard coming from the mouth of any birder at some point in time, but what does it all mean? These are all terms for different parts of the body that may be used to point out a field mark. Below is a White-throated Sparrow, which isn't common here in Colorado but their facial patterns are nicely defined.



Primary and Wing Projection can be a confusing set of terms because they both relate to the length of the primaries but the object of comparison isn't the same. Primary projection is the length of the primaries. Some birds have shorter primaries than others. Wing projection is how far the wing goes past the tail. The long wing projection (the wing going past the end of the tail) would be one indicator of this being a Swainson's Hawk. Its also good to make note of the Cere, which is the fleshy yellow spot just above the beak. This is present on all raptors.
 
 
 
Feather group names can be important in certain situations. The photo bellow is an exotic species, the Mandarin Duck, spreading its wings showing us all those lovely coverts. 

 
The black lores on this bird tell us its a male Yellow-breasted Chat
An eye ring is a white outline around the eye.
 They can be found in some flycatchers,
 warbler, kinglets and many more.
This McGillivray's Warbler is showing a broken eye ring.

Notice the complete eye ring on this Field Sparrow
 
These are just a few of the really common ones if you can't read one of the photos let me know and I'll enlarge it. There are many more terms that can be applied to parts of the bird that aren't used in everyday situations but are still interesting. If anyone is interested in knowing some more specific terms I can create a part 2.

Identification Tips #1 General Tips

Least Flycatcher
 
I'll be using photos from a bird banding station because that way you can get an idea of size as well as a better view of an field marks
 
Identifying birds can be a daunting task when your flipping through you field guide trying to find a small maybe yellow-olive bird that you saw while hiking up Guannella pass. If you break down what your seeing on the bird as well as the habitat around you and the noises your hearing it can make the id process much smoother.


The book
One thing I remember doing was flipping through my favorite field guide just looking at the pictures of the birds and noticing how they are organized. This is something I recommend doing whether your a beginner or advanced. Looking through your book can give you a good idea of what your looking at in the field. but don't forget to look at the real bird while its there gather information on its plumage details and behavior, back up what you saw later looking at the book. You wouldn't want to miss views of an incredible bird looking for it in the book.


This large bird is common in urban areas and loves suet!
 Its long beak and tapered tail feathers point to woodpecker her
 red underwings/ tail spotted breast and bib point to Northern Flicker.
Her lack of a red malar (or mustache) says she's a girl
Rule out what its not/ Plumage
You can rule out what a bird isn't by many different things, plumage colors and pattern, size, shape, bill shape and size, habitat, range, behavior and time of year, once you narrow down what it isn't you can focus on the fewer option you have left.
When your looking at a bird notice its color. Is it a bright color? or a more earthy color. Notice its size. Is it larger or smaller than the typical American Robin? Does it have any noticeable features? Streaks or spots on the breast? an eye ring? light eyes, dark eyes?
If your looking at a blackbird in a parking lot with yellow eyes you have now narrowed it down to two choices! Brewer's Blackbird and Common Grackle. (unless your out east then Great-tailed Grackle is another possibility)

Habitat
Different birds live and specialize in different habitats. Familiarize yourself with the various habitats in your area and the plants and bird species of those habitats.
Here are a few along the front range

Lowland Riparian
areas of tall cotton woods and thick underbrush of chokecherry, wild plumb, and willow all along a lake, river or stream.
common birds of these areas are
Yellow Warbler
Bullock's Oriole
House Wren
Broad-tailed Hummingbird
This bird is much smaller than the flicker has a shorter bill and a striking head pattern.
 This size and "earthy" colors on this bird point to sparrow. You can see in this
 photo but he has a clear breast. (no streaks)
 the white head stripes points to White-crowned Sparrow

Scrub Oak
foothill areas covered in Gambel's Oak, juniper, Three-leaf Sumac (skunkbush) and Mountain Mahogany
often housing
Spotted Towhees
Western Scrub-Jays
Blue-grey Gnatcatcher
Virginia's Warbler

Emergent Wetland
marshy areas composed of mostly cattails or rushes
houses
Marsh Wrens
Herons (many types)
Red-winged Blackbirds
Common Yellowthroat

Behavior
Watching a birds behavior can also be an indicator of what species or even what family it belongs to.
If your watching a bird sitting upright on a branch and it suddenly flies out in a little circle and comes back repeatedly it is probably a flycatcher.
If your watching a small brown bird skulk around in the bushes while wildly scolding you, you may have a wren.

Time of year
Birds migrate. Warblers leave, orioles leave, most thrushes, many herons and blackbirds leave (Colorado that is) for more abundant resources down south. On the other hand many birds arrive in the winter as well. Raptors are much more abundant in the winter and ducks! Many different kinds of ducks winter in Colorado and they are all unique and very vibrant! Make sure when your considering a bird that it has a pretty good chance of being in your area at the present time of year.
In the late summer and fall juvenile birds outnumber adults. This makes for very difficult identification on some species such as sparrows. Be trying to find an ID consider the juveniles as they often look much different than the adults.

These are just a few things to consider when looking at a bird. Think about one at a time focusing on the bird while its in sight. You can later consider other things but its very important to look at the bird itself.

This bird is a little different. Its smaller than the flicker and smaller than the WC Sparrow as well. It has a long tail, thin bill, yellow throat, wing bars (messy wing bars) and a beautiful patter on the tail. The small size bill shape you lead you to warbler. It has a much thinner longer bill than the sparrow. From there you'd look for birds with mostly grey body and yellow throat. Hopefully you'd arrive at Yellow-rumped Warbler even though you can't see the yellow rump in this photo.

Hudson Garden August 10th



On August 10th Britny, myself and 9 other people gathered at the Hudson Garden gift shop for our Saturday walk.

We saw few birds until we reached the Platte where birds activity was plentiful! Yellow Warblers are still singing and Northern Flicker's were calling from the tall cottonwoods. We made our way up the river watching the Mallards float by while discussing the males in eclipse plumage (Males with a yellow bill and orange feet while females have an orange bill and orange feet). Arriving at the bridge we glassed the water for Wood Ducks and found a single eclipsed male mixed in with 15 or some Mallards.

An adult Double-crested Cormorant sunned itself in the center of the river its jet black plumage and green eyes reflecting in the sun. While admiring this textbook adult a juvenile paddled down to a rock nearby. We noticed the overall buffy look to the juvenile compared to the adult.

We had lovely views of 3 herons species Great Blue Heron, Black-crowned Night-heron and the slender Snowy Egret.
Snowy Egret

We made our way across the river to a small adjoining pond where we watched Barn Swallows and talked about how to tell the differences between the species perched and in flight. On our way back to the coffee shop we had great views of Cedar Waxwings catching insects out above the river. We ended the day with a mystery juvenile Grosbeak on the Hudson Garden's hopper feeder. Initially we thought Black-headed and it slowly turned to doubt as we noticed a stain of red on a breast as well and red under wings as it flew past us disappearing into the locust trees. We were never able to relocate the bird but we're still leaning toward Red-breasted Grosbeak. We ended the day with 25 species.

California Coast Point Reyes



Hotel on Tamale Bay
Western Scrub-Jay
Point Reyes is famous for its variety and number of species during the migration and summer months. I wish I'd done a little more research about what places to go before getting there but I was pleased with the many interesting things we saw.  Our hotel was right on the edge of Tamale bay where my sister and I found many new creatures including barnacles (which are actually crustaceans), tiny crabs, terns and even some sort of ray that was floating just bellow the surface!
Right outside our window there were a few bird feeders that were frequented by Western Scrub Jays and House Finches.

Caspian Tern
Our first adventure at Pt. Reyes was to the lighthouse where the wind blew so hard I had to back up to the rocks to keep my balance! I brought my scope up but it was almost useless because of the biting cold wind. The birds though! It was amazing. On the walk to the light house White-crowned Sparrows sang continuously and a lone windblown Rock Wren was even singing! The stairs to the actual lighthouse where closed but the fenced look area was plenty for me.

Far bellow us tiny dots where constantly flying around, when I finally got a scope set up I could see cormorant, guillemots, and gulls all flying to and from the cliffs. For every bird I managed to identify at such a great windy, misty distance there were 20 or so that I could hardy see. The cormorants I was completely lost on. Every time I saw one I thought I could ID it would move slightly and turn into a another species. I decided I'd wait to see cormorants at a different location (and the patience paid off).

Common Murres
Cliff Side
On the right side of cliff was a large rock that held thousand and thousands of Common Murres, and hundreds were leaving at one time and hundreds were landing all at the same time. I scanned that rock and the surrounding one over and over looking for puffins and auklets but did not find any. As we turned to head back to the parking lot I glanced down the cliff one last time to attempt to count the birds on the water when a Peregrine Falcon flew by! We were all freezing at this point and decided it was time to leave. Next was Chimney Rock.

Pt Reyes Light house
Chimney rock wasn't nearly as birdy as the lighthouse but it held a breeding colony of Elephant seals and just off the shore a flotilla of Surf Scoters! While admiring the scoters Savannah Sparrows, American Goldfinches and White-crowned Sparrows sang in the fields behind us. We never actually mad it to chimney rock as it had been a long day of travel and hiking and it was time to head back.

View from the lighthouse


Day two at Point Reyes was an interesting one. We'd planned on going to the banding station there but the one we found was closed because of the wind. While deciding where to go next I spotted Chestnut-backed Chickadees, Anna's Hummingbirds, Band-tailed Pigeons, and a Bewick's Wren! All while I was standing in the parking lot. While standing around one of the interns informed us of another banding station in the park that we should try. They said it was a better station and had more birds. We piled in the car and headed on over.

So far all my experience with banding stations has been through Rocky Mountain Bird Observatory. They take more of an educational stance with banding. The Pt. Reyes Station was almost strictly for scientific study. They had no table, three banders and no excited children standing around. They banded, measured, weighed and let the birds go. Fast and efficient. They had twenty to thirty birds on their hooks which is often more than we catch in a day at Audubon. It was here I saw my first Wrentits of the trip! So far I'd only heard them mocking us from the bushes. Seeing them in the hand was very exciting. 

Wrentit in the net
 Our last stop at Pt Reyes was Abott's Laggoon. It was supposedly the best spot for migrants. Of course being there in mid June I didn't see many migrants. Abbott's Lagoon was hot and a little slow. Many singing Sparrows, Savannah and Grasshopper but we didn't see very many shore line type birds.
We passed a Great Blue Heron sitting in a tree and moved onto the sandy bank where we found a strange mystery bird sitting on the shore panting. Its feet sat way on the back of its body, it was slender and had a long slightly upturned bill. I new it had to be a loon of some sort but living in Colorado I have not had the chance to get a good look at many loons. Upon returning I posted the photos to facebook (of course) and immediately it was IDed as a Red-throated Loon based on its light plumage, and upturned bill. Loons don't usually sit on the shoreline nor do they breed in California so I'm not sure what was goin on with this guy.
