不要錯過哈 - 賓州中溪雪雁大遷徙

(2017-02-04 05:28:43) 下一個

屈指一算，去年賓州看雪雁都快一年了。趕緊補寫遊記。知道嗎？賓州的中溪Middle Creek，就是攝影師夢寐以求的打鳥天堂。每年二月底至三月初，數以萬計的雪雁，在墨西哥灣過完冬，返回加拿大繁殖，中途停在中溪休息。雪雁每年都要經曆兩次2500英裏的飛行，3000英尺的高空，飛行時速40-50英裏，蠻辛苦的。而且，人家吃的隻是草和穀物啊！除了佩服還是佩服。雪雁數量和時間很難預測，完全看天氣冷暖冰雪情況而定。

可以跟蹤官網雪雁預報:

摸索了小小經驗，觀看拍攝雪雁最好時間是：

1.下午至日落之間，天黑了它們就下到湖麵不動了，漆黑一遍，啥也看不見，隻能聽到叫聲。

2. 天蒙蒙發亮至日出之間，太陽一升起來，全飛走了。如果要看日落和日出，最好在附近住一個晚上。

我們是2016年3/11號下午3點到達的，已經有很多雪雁在湖麵，湖邊草地了。

當時看了一會，估計它們也不幹嘛的，就走去停車場拿本書和衣服回來，風大的時候，挺冷的。

10分鍾而已，結果，結果最大的那一群雪雁，鋪天蓋地的瞬間在湖邊起飛，在人群的頭頂上方，伸手就能摸到的距離，輕輕的飛向遠方。。。

最壯觀的那一刹那，我，完美錯過了。當然，遠遠的也能看見，感覺完全不一樣。錯過了就錯過了，因為當你不知道你錯過了什麽的時候，是無所謂滴。可是那老棉襖，三番五次的，喋喋不休的嘮叨“可惜吧，那麽壯觀。。。”

後來，真的沒有那麽大群在頭頂上空飛過了。所以呢，過來人的經驗之談，到了以後，千萬不要離開哈！其實它們隻是飛到不遠的一塊大草地，黃昏時再一群群的飛回來湖麵過夜。

雪雁是這樣的

突然吵雜聲越來越大，然後就。。。

壯觀！

飛來了這裏，換個地方休息。

黃昏，雪雁開始回來。

一輪明月

次日清晨5點就爬起來離開酒店，到達湖邊，眾多大師長槍短炮的對著湖麵，等待著。。。

太陽冉冉升起，幾萬隻雪雁從湖麵飛起，場麵之壯觀，用任何語言來形容都會顯得蒼白無力的，隻能用感歎詞哇塞，OMG，Wow, Wow......

半小時後全部飛走了。

七點就開飛了

恩恩愛愛

雪雁遠走高飛了，天鵝的天下了。

野地裏的野雞

Lancaster是Amish聚居地，原始的鄉村風味。

謝謝觀賞！

完了可以順路去長木公園Longwood Gardens玩玩

看看那個珍稀的喜馬拉雅山花：

These few birds continue to linger, but they won’t be here much longer and the big numbers are not likely to return.

Snow geese: less than 5,000

Tundra swans: 200
Canada geese: mostly gone

03/13/2016:

Snow geese:
                   Friday - 50,000
                   Saturday - less than 20,000
                   Sunday - less than 5,000
Tundra swans: 200

03/11/2016:

Numbers appear to be holding steady. Saturday’s winds are forecasted to be blowing from the south, that should get birds moving. We’re unable to update the website on weekends, next report will be on Monday.

03/10/2016:

Swan numbers came up again yesterday, but it looked like a lot of those birds may have left for good this morning. Canada geese continue to pass over, heading north in large numbers. Snow geese tend to leave a little later than the Canadas and swans, but we’re nearing mid-March and I would expect we’ll see numbers drop with the next south wind.

Snow geese: 50,000 steady for now
Tundra swans: 1,200 dropping

03/09/2016:

Snow goose numbers are holding steady for now, swan numbers appear to have dropped dramatically, and Canada geese are streaming north.

03/08/2016:

Snow geese: steady
Tundra swans: 2,000 +

03/07/2016:

Numbers were up, then they went down, then they came back up. The waterfowl migration is in full swing, warm temperatures and favorable winds might convince birds to leave and head north this week.

Snow geese: 50,000 +/-
Tundra swans: 1,600 +

03/04/2016:

It is apparent that snow goose numbers went up somewhat yesterday. Unfortunately no good current estimate is available, perhaps 20,000 or more. There are also reports of snow geese to the north of us, birds are moving. The duck migration has really picked up, lots of ducks of several different species present.

03/03/2016:

Yes, I was very surprised by this development too. The current cold-snap we are experiencing should not have been enough to drive that many birds back to the south. While there are birds moving north I would not have expected birds migrating through this area to be gone already. Since this seems to be a more “normal” spring, and it’s still early on the calendar, I would have expected to have lots of birds into mid-March. There is a possibility that birds are using a different waterbody nearby or they may have spent the night out feeding. Also, during the spring migration birds that push north may be replaced by birds still coming up from the south. To be honest I was surprised when I took a look at the lake this morning, saying to myself “where’d they go”? I’m not sure how this will play out, stay tuned.

Snow geese: less then 15,000
Tundra swans: less than 1,000
Canada geese: few

02/29/2016:

The buildup in numbers started late last week, waterfowl are on the move. Based on the behavior of some of the flocks of Canada geese and tundra swans this morning they may have pushed north when they left the lake this morning; migrating Canadas were passing over from the south to the north as well.

Snow geese: 65,000+
Tundra swans: 3,500+
Canada geese: lots
Ducks: a diversity of species

02/23/2016:

Snow geese: 30,000+

02/22/2016:

Some snow geese showed up on Saturday and more came in at first light this morning. There has been some movement of waterfowl lately, we’ve picked up some ducks and Canada geese, swan numbers are holding steady.

Snow geese: 20,000+/-

02/18/2016:

A few thousand snow geese showed up yesterday and a couple hundred more came in this morning, there is still very little open water on the lake.

Snow geese: 5,000+

02/16/2016:

The snow geese that were here last week left when the big freeze hit by the weekend, surprisingly the swans are toughing it out. The only open water remaining is off of Willow Point which is currently the best place to see whatever birds might be here. Today temperatures are in the forties and it’s raining which should eliminate most of the snow and perhaps some of the ice.

Snow geese: none

02/11/2016:

I got a better look at swan numbers this morning, I’m surprised that there’s this many here given the conditions. The band of snow geese is still here too even though there is not much open water on the lake. Short-range weather forecast is calling for bitterly cold temperatures, numbers will probably not increase until we experience a thaw.

Canada geese: several hundred
Tundra swans: 1,300+
Snow geese: 5,000+

02/09/2016:

Warmer temperatures and rain melted much of the snow that was here last week and a few thousand snow geese showed up. However, it is now snowing again and temperatures are expected to plummet in the near term which should put the brakes on waterfowl migration.

Canada geese: several hundred
Tundra swans: several hundred
Snow geese: 5,000+

02/02/2016:

First Report of 2016: Lots of snow and ice are keeping things pretty quiet, not many birds here. Until conditions change dramatically it will probably remain this way. It is also still early on the calendar for birds to be on the move.

Canada geese: several hundred
Tundra swans: several hundred
Snow geese: none

Snow geese: 110,000 on 03/15/15

Tundra swans: 3,000+ on 03/27/15
Canada geese:1,800 on 03/16-12/15

It was the coldest February/March combination on record locally, and the ice-cover on the lake bore testament to that. I've long held the belief that open, ice-free water is a prerequisite before large numbers of the large waterfowl will show up. That was not the case this year, the birds had no choice but to roost (sleep) on the ice if they were heading north. The photoperiod (the amount of daylight) is what really drives the migration, although it is affected by weather conditions. As days get longer in the spring birds that migrate get the urge to start moving back towards their breeding grounds, sometimes regardless of conditions. It was an interesting migration season, they all are.
