Breeding Birds

June is definitely all about breeding birds.  As Lynn mentioned earlier, most species we see with their "feet on the ground" here are breeding birds.  The campus grounds has abundant habitat for those birds adapted to suburban survival - with shrubs, lawns, mature trees and some wild and weedy areas being our prevalent habitat types.

I'm always surprised when I find our Wood Thrush still singing away on its territory - a small patch of hardwoods with a fairly open forest floor and adjacent dense tangles of invasive vines and shrubs.  Recent research on the habitat needs of this species indicates that although it is a fairly common breeder in small forest fragments such as ours, its breeding success rate is higher when it occupies larger forested areas.

Above, one of the pups from our coyote family - a typical coyote sighting for most Connecticut residents.
And here's a different pup from the family, taking the sun about 3 meters from a parking area - a typical coyote sighting for us at West Campus
With Mama Coyote and four pups around, it's no wonder we see very little of our turkey flock these days, and the resident Red-tailed Hawks are actively hunting on campus, making the squirrels, chipmunks and rabbits not as visible as they sometimes are.

So, Lynn and I both had time to get out birding this week, and here's the result of our modest effort:

Back to Birds

After months of planning, the 27th annual meeting of the Society for the Preservation of Natural History Collections finally took place at the Omni Hotel in New Haven, CT.  The Yale Peabody Museum of Natural History was the host this year and much of our collections staff was involved in the planning and hosting of this amazing event.  It went off great!  Now that it's over.... we can finally get back to the birds.

Sue and I have had almost no time for lunch time walks or keeping our bird board up to date.  The first thing we did on Tuesday morning (after the meeting), was wipe down the birds to start over fresh.  The weather's been jumping around with a heat wave of 3 consecutive days over 90 degrees (that's what a heat wave technically is) to overnight lows last night of somewhere near 60.  Everyone on campus at this time of year are likely breeders.  Of course some are just passing over.

Weekly species tally

Bird list for the week of May 14-18, 2012
Mourning Dove
House Finch
Downy Woodpecker
etc
etc
Here's how we keep our weekly tallies at West Campus:

Panel 1
Panel 1 - top, middle and bottom
The bird names stay in place on these glass panels and we mark the day of the week when seen.  Panel one (shown in the three images above) is the regulars, those we're likely to see nearly every day.  We shift to the second panel as more species move through West Campus, and add names in the order of occurrence.  When winter is over, we remove strictly winter birds from the first panel and fill in those gaps with spring and summer birds.

Panel 2

Panel 2, top, middle and bottom
 The second panel, shown in the above three images, is a mix from common year-round species (Rock Pigeon) to early spring migrants (Barn Swallow).  Some of the spring species just pass through on migration and are not seen again until fall, so these will be removed from the list in a few weeks time, when the likelihood of seeing them diminishes.

Panel 3
  
Panel 3, top, middle and bottom
As we fill the second panel, we round the corner to the last panel (above three images) which shows only the most recent arrivals - including our first of the year Blackpoll Warbler.

The records I keep here on the blog do not include these daily observations, so these data are lost.  However, the weekly tallies reflect the frequency and duration of our birding outings, inasmuchas we have to be in the right place at the right time.  If we don't get out much, we don't see the birds.  The Blackpoll Warbler might have been out there on Wednesday - and Friday too, but Thursday was the day Lynn was there and saw the bird - so it goes on the list for the week.

Turkeys, Hawks, and Eggs, Oh My!

I guess I (Lynn) will do a little text for our birding this week.  The story of the week was definitely the Turkeys!  On my way into work one morning a lawn mower chased me down...  He really did, one of the grounds crew wanted to show me something interesting.  He brought me over to a low stone wall and there sitting on top was this egg.

A Turkey egg!! laid directly on a stone wall.

I brought this cell phone picture back to Sue who agreed that it was a turkey egg.  I have seen a female hanging out near this area for a couple of days all by herself.  My guess is that she was a young (1st year) female who hadn't gotten the knack for being a Mom yet. 

Another morning I passed Sue and her sister Karen on my way up to the building and they said that a Red-tailed Hawk was making passes at a couple of turkeys.  By the time I made my way up there the female turkey had walked away a little but these two males near by were still strutting around.

Two Tom Turkeys trying to impress a female (out of sight just now).
When I glance in a tree behind all of this turkey action I caught sight of the hawk... or rather hawks.  Assumably this is a pair of red-tailed Hawks and the male was probably showing off for the female by taking a few swipes at the turkeys earlier.  Here the hawks are taking a rest and bonding.  So, which one is the male and which one is the female.....  you can make a guess using the info below.

Red-tailed Hawk pair, usually seen overhead, but Monday morning found in close proximity to each other, and to us!

"The red-tailed hawk averages 19 to 24 inches in length. There is sexual dimorphism in size: females are 25% larger than the males. Plumage ranges from light auburn to deep brown. The underbelly is distinctly lighter than the rest of the body, with a dark belly band across it. The cere, the soft skin at the base of the beak, the legs, and the feet are all yellow. The eye color of the hawk changes from yellowish gray when immature to dark brown in adults. " -Lake Milton Raptor Center 

Did you guess?  Based on this photo I would say the higher bird is the male although these two are very close in size.  So yes the female is usually larger but everything has variation and this pair is probably made up of a larger than usual male and a smaller than usual female making them relatively close to the same size.  This neighbor below was not too happy to have all this activity so close to his nest!

Northern Mockingbird in a maple.

Special this week - spring plants AND reptiles


Red-tailed Hawk (Buteo jamaicensis) flying "fairly close" overhead. Since the bird-life of West Campus is usually too distant or too active for my little camera, I tend to focus primarily on the nature at my feet.


Marsh Marigold (Caltha palustris) growing in the gravelly river bed at West Campus. Along with the Trout Lily (photo in previous blog post) this yellow-flowering plant is one of the earliest spots of color in the still-brown New England woodlands in April. The sap can be an irritant to sensitive skin.


As I photographed plants along the river's edge, I disturbed a basking Garter Snake (Thamnophis sirtalis). One of the most commonly encountered snakes in New England, this individual shows the typical coloration of buffy-yellow stripes against brown. This is a snake with wide regional color variations, with some subspecies exhibiting bright yellow or even orange stripes against a dark green or black body.

The warming days prompt snakes and turtles to emerge from winter hibernation. If you take time to sit quietly near a wetland or stream, pay attention to every rustle in the leaf litter. Wood turtles (Glyptemys insculpta), water snakes (Nerodia sipedon) and many other reptiles are on the move.


Wild salad - Garlic Mustard (Alliaria petiolata) in front of Wild Onion (Allium sp.)
Allium is the genus of hundreds of species of garlics and onions. Alliaria means "like garlic", referring to the scent of garlic that emanates from the broad-leaved plant when crushed.

Straight from Wikipedia:
Garlic mustard was introduced in North America as a culinary herb in the 1860s and is an invasive species in much of North America. As of 2006, it is listed as a noxious or restricted plant in the US states of Alabama, Connecticut, Massachusetts, Minnesota, New Hampshire, Oregon, Vermont, West Virginia and Washington. Like most invasive plants, once it has an introduction into a new location, it persists and spreads into undisturbed plant communities. In many areas of its introduction in Eastern North America, it has become the dominant under-story species in woodland and flood plain environments, where eradication is difficult.


At West Campus, this plant is particularly vigorous down in the woods along the Oyster River. Each year, Tom Parlapiano gathers volunteers to wage an eradication campaign.

Nest Box maintenance

Cavity nesters are around, or arriving soon, so we're getting our man-made cavities ready for them. A few weeks ago, Tom Parlapiano made the rounds of the small boxes - the ones we've put up to attract tree swallows, bluebirds, wrens and chickadees. His goal was to clean out old debris - from last years' nests or from overwintering rodents.


Tree Swallow nest box at West Campus, all spruced up for spring.

Earlier this week, Lynn and I carried the twelve-foot ladder out to tend to the Kestrel box, and sadly found it quite occupied.
First step is to rap on the box to evict possible rodents. Check, done, nobody came out.
Next step unlatch side panel to see what you have. Check, done, a big pile of leaves and grass. Looks like a rodent nest.
Okay, start to remove the debris, a handful at a time. After three fistfuls of stuff, Lynn stopped, having uncovered a motionless gray squirrel.

Well it was breathing. Why hadn't it run? We guessed perhaps it was a female with newborn pups, so we let her be without disturbing her further. We don't need more squirrels around, but neither did we want to be needlessly cruel -- we should have checked much earlier. Lesson learned.


Our kestrel box is occupied.

Happy to report that we've had a few new birds already this week (writing this on Wednesday, since we have Friday off).
In boldface are birds we haven't seen since last fall
