Egypt - Early Bird Migration Noted

[sharon sanders]

Migration of the early birds fall

سجلت أجهزة الرصد ومراقبة الطيور بمحمية الزرانيق بمدينة العريش هجرة مبكرة لطيور الخريف قبل موعدها بنحو 25 يوما في رحلتها من أوروبا عبر البحر المتوسط لمواصلة طريق هجرتها إلي أفريقيا عن طريق محمية الزرانيق.​

Registered monitoring devices and control of bird protected Zaranik Areesh City early migration of birds before the fall schedule by about 25 days in its journey from Europe across the Mediterranean to continue through their emigration to Africa through the protected Zaranik.

صرح المهندس عبدالله الحجاوي مدير إدارة البيئة بشمال سيناء بأنه قد شوهدت عدة أسراب من طيور البلاشون والنورس والبشاروش وبعض الأنواع الأخري.​

Does the 25 days difference from the "normal" migration date represent a statistically significant difference?

In other words, could it not just be by chance that the migration is happening 25 days early?

Similarly with Alaska'.

"Summer migration begins in early August when water bird migration begins at Zaranik in North Sinai and White Stork migration begins in the southern Gulf of Suez. "

Sounds "normal" rather that "early". Not a good indicator of climate change, then.

Re: Egypt - Early Bird Migration Noted

This hasn't been a typical 'climate change' year, Cartski. Bird migration timing - especially in Spring, as you well know, has shifted for many species by as much as 3 weeks with respect to historical norms, but that value within any given year may be a function of prior season conditioning, forage quality, and local temperature anomalies.

In the dog days of summer in the deserts of North Africa, the sum toto climate change effect at present is 1.0 for Cairo and 1.1 for Tel Aviv, in line with the global value of ~1.03 (having just attained a value of 1 in the past week, after months of low tenths values).

In fact, in parts of Europe, they are finally seeing 'summerlike' weather.

Re: Egypt - Early Bird Migration Noted

Yes, I know that this has not been a normal migration year. But that's an intuitive assessment from my observations, or extrapolated from the stories from others.

I'm not trying to be argumentative. I'm just wondering if there is some sort of index, or more statistical evaluation of migration patterns. A newspaper reporters' assessment of "early" isn't enough.

But maybe you have an index with "sum toto climate change effect"? What is this, and where is it from?

Thanks,

... "sum toto climate change effect"? What is this, and where is it from?

Maybe O. means total, the total summary of climate change effects without statistical reviews, which are visible naked eye by every of us if goes to expose a naked skin to the sun's now very burning lights,
the melting evidence of the glaciers (why alpinists perceived as nothing happened, when it's obvious the old and new routes are fallaceous because of warming crushings).
The populations in contact with real nature can see if unusual migrations are on place, or better, if in an area (for that area) new bird species established their nests.

But we always aspect that few decades passed before action,
waiting is our defence.
As Pompeians when birds fly offs from the volcano area ...

This sounds like a more systematic index system published by some renowned environmental entity.

Analogous to the report card systems used by Sierra and other entities.
