February Flowers

In eastern Pennsylvania, February is not usually considered a month when many flowers begin to bloom. However, the unseasonably warm temperatures over the last week and a half have caused many early-blooming species to emerge. Many of these species are flowers that will begin to flower as soon as there is an extended period of warm weather, so the bloom time varies greatly from year to year.

Snowdrops (Galanthus nivalis) - this species was blooming around this time last year as well. Warm weather usually causes the flowers to develop, although it takes several warm days for the flowers to actually open. Although the flowers are not yet open in the photograph, these flowers began to open on February 26.

Winter Aconite (Eranthis sp.) - With several days of sunlight, this flower is now in full bloom. This species began blooming last year around February 18, which is about the same time I first saw these flowers emerge in 2012.

Bird's-eye Speedwell (Veronica sp.) - This flower has actually been blooming through the entire winter. The flowers open in the sun, but close during nights and during colder days. This species grows very low to the ground and is easy to miss.

Primrose (Primula vulgaris) - This species is not quite ready to bloom, but a closed flower is visible amongst the basal leaves.

Bittercress (Cardamine sp.) - This flower could easy go unnoticed, as the small flowers grow very close to the ground in weedy areas. I found several hundred of these tiny plants blooming in my yard this week.

Crocus (Crocus sp.) - This is a very common early-blooming flower that can be found in a variety of colors, including yellow, orange, purple, pink, and white. Last year, crocuses did not start blooming in Kunkletown, PA until March 3. This year, the first flowers were seen on February 19.

Purple Dead-Nettle (Lamium purpureum) - This species is a common weed of gardens and lawns. This is the earliest I can remember seeing this species blooming. The flowers can sometimes be similar in color to the leaves, so if you find this plant, look carefully for flowers, as they may be hidden.


Skunk Cabbage (Symplocarpus foetidus) - Today (February 26) I found the first open flowers of this wetland plant in Kunkletown, Monroe County. The combination of red, yellow, and green on these unusual flowers make Skunk Cabbage and easy species to spot. (Photo from 2011)

Year two of the Eastern PA Phenology Project begins

I have been receiving reports of birds singing, new sightings of birds that were away for the "winter", and many have noted that it even now smells like spring.  I know what they mean, but cannot put that into words.

Today, a large flock (4000+) of snow geese and flocks of Canada geese were heading north over Kunkletown.  It has been a delight to see the snow geese for several months in the Lehigh Valley, but there numbers are decreasing and they seem to be more restless, perhaps preparing for the trek northward.

For comparison, here is what we posted last year on February 19th:  http://watchingtheseasons.blogspot.com/2011/02/it-cant-be-spring-already-can-it.html

Birds singing

This morning on my daily walk with my dogs at daybreak, I heard a Northern Cardinal singing. Yesterday, I heard a Mourning Dove. These are the first bird songs of the season that I have heard for these two species. They seem to be thinking spring.

The winter that hasn't been

So let’s start today’s post with some weather data from the National Oceanic and Atmospheric Administration NOAA for Allentown, PA comparing the average monthly temperature for fall and winter 2011/12 vs. the 1981-2010 averages for these months:

September '11:          67.3⁰F vs. 64.3⁰F
October '11:               53.8⁰F vs. 53.1⁰F
November '11:          46.6⁰F vs. 43.3⁰F
December '11:           38.4⁰F vs. 32.9⁰F
January '12:               33.3⁰F vs. 28.5⁰F

The annual average for the entire year of 2011 was 53.2⁰F vs. 51.7⁰F. 

This type of information can be found at http://www.nws.noaa.gov/climate/xmacis.php?wfo=phi

The last I heard from the WNEP meteorologists (Wilkes-Barre/Scranton area), we are on track for having a winter with the least amount of snow in at least 60 years.  The freak snowstorm in October technically didn’t occur in “winter”.  There are deficits in snowfall around the country, but parts of Alaska and Europe are experiencing unusually heavy snowfalls compared to their norms (whatever that means any more).    A good source of information about weather patterns, changes, and extremes around the globe: http://classic.wunderground.com/blog/JeffMasters/article.html

Forsythias blooming -- at the end of November?
Wonder what the spring bloom will be like?

So what happens in nature when the temperatures have been unusually mild and the snowfall almost non-existent?  Going back to November, I had reports of the forsythias blooming from Saucon Valley up to Scranton.  Throughout the late fall, there were numerous reports of dandelions (even at the end of December) and flowers on Creeping Phlox (11/22 in Easton), ground ivy (end of December in Bethlehem), and Hellebores (Bethlehem).

In mid-November, there were reports of skunk cabbage emerging in the Lehigh Valley.  Such early reports have continued with reports of blooms on January 1st from the PPL Riverlands and Bottomlands along the Susquehanna River to plants emerging in Sciota (Monroe County, north of the Kittatinny Ridge) on February 3rd.

Today (February 5th), the buds of the aconite and snowdrops were almost open.  Last year, they opened on February 18th and that was early for north of the Ridge.  Snowdrops have been blooming in Bethlehem for over a month.  Several people have reported that the daffodil plants have emerged by several inches.  The tiny-flowers of the creeping speedwell (a Veronica) have been blooming throughout our yard since December.

Aconite
Bald Eagles will stay around as long as there is open water for them.  They have been reported in Wyoming County into early January and again this past week.  Last weekend we saw them flying along the north edge of the Kittatinny Ridge.  The snow geese have stayed at Green Pond and the surrounding flooded fields since that area hasn’t frozen over.  The swirling flocks in early morning and late in the day are quite an awesome sight, especially when the sunlight hits them just right.  It is worth the drive to see the shimmering rows of pearls rising and twirling over the fields or flying in large flocks overhead.  The forty year Pennsylvania winter population of snow geese has increased almost 270,000 % according to data from the Audubon Christmas Bird Count (a thank you to Greg Butcher from Audubon for this information).  This rate of increase is significantly higher than the continental trend.

I have had several reports of Black Vultures north of the Kittatinny Ridge from Monroe to Luzerne Counties.  Over the past forty years, the winter population of this species has increased in the state by about 83,000%, again rising at a rate higher than the continental trend.  We have also been seeing Turkey Vultures north of the Ridge over the past two weeks.  While it is not unusual to see vultures in the Lehigh Valley and southward over the winter, it is quite unusual north of the mountain.

According to the PA Birds List Serve and eBird, there have been reports of American Woodcocks (January 4, 2012 in southern Chester County; January 7, 2012 in Berks County, January 8, 2012 in Schuylkill County; and January 31st in Pottsville).  We expected to hear them hear when the temperatures hit the 60’s this past week, but didn’t perhaps because we got home from school and work too late in the day.  Be on the lookout for Woodcocks and let us know when and where you see (or more likely hear) these.

On January 31st, a Gray Catbird was reported in Wilkes-Barre.  And yesterday, at the Eureka Road Pond near Snydersville, a pair of mute swans was observed, with the male going through some mating ritual behaviors.

Yesterday, my retriever brought me something in his mouth.  It turned out to be a frog (probably a wood frog)!  We suspect it came out when the temps reached the 60’s earlier in the week, but didn’t survive the cold night.  Very strange.

Last year, we planned to launch the Eastern PA Phenology Project around March 1st.  We had mild weather in February, and soon realized that events of nature often associated with spring were already happening.  With the even milder winter weather this year, there should be all sorts of seasonal changes to report on.  We invite you to participate in the project.
