Upton Warren (48 Viewers)

Black Tern Chlidonias niger

First recorded at Upton Warren on the 23rd April 1941 (A. J. Martin), this species is regularly reported in spring on its northward migration from the coasts of West Africa to its East European inland breeding marshes where it has a breeding population of up to 70,000 pairs (it ceased to breed regularly in Britain in 1884). Annual totals can vary greatly with occasional influxes, especially following the breeding season, which can result in the arrival of large flocks. As with many other tern species, gloomy humid weather, storms or strong winds often provide the ideal conditions that result in the arrival of Black Tern flocks.

The average first date of arrival up to and including 2007 was the 2nd May, with a marked peak of records in early May. The earliest bird was at the Moors Pool on the 16th April in 2015. Birds can be recorded late into the year with a drawn out autumn passage between early August and late October, often involving juvenile birds. The average last record up to and including 2007 was the 25th September. Occasionally birds are reported right until the end of October, especially when there is an “Indian Summer”, with the latest report being on the 30th October in 1990. Although most birds pass through the reserve in a day, there are near annual records of birds (often juveniles) which take up residency for a few days, such as the juvenile which spent four days from 7th September 1992 roosting on the floating bistort at the Moors Pool or another juvenile present at the Flashes from the 14th October until the 29th October 2000 when it was forced off by floods The annual report for the West Midland Bird Club considers the October 2000 record to be the same as a bird seen in late September, resulting in a 32 day stay between the 28th September and 29th October 2000, believed to be the longest staying individual observed in the West Midlands region.

The 100 records between 1984 and 2014 are distributed as follows, showing a clear peak to Spring migration in early May but a much more drawn out return passage from early August right through to October:

April - first half: no records
April - second half: 14 records
May - first half: 32 records
May - second half: 11 records
June - first half: 5 records
June - second half: 6 records
July - first half: 1 record
July - second half: 1 record
August - first half: 9 records
August - second half: 12 records
September - first half: 15 records
September - second half: 11 records
October - first half: 3 records
October - second half: 4 records

A peak count of 64 birds was seen on the 11th September 1992. During the early morning the total of birds at the Moors Pool increased to reach a single flock of 53 birds (predominately adults) by 8:30 am. As birds came and went the total number rose to at least 64 by the end of the day. This represented only a small part of an unprecedented movement over several areas of the country, with the West Midlands recording 1,952 birds during the day on the back of strong westerly winds. These included 350 at Draycote Water, 300 at Blithfield Reservoir, 250 at Belvide Reservoir, 205 at Westwood Pool, 194 at Coton Pools, 100 each at Bittell Reservoir and Earlswood Lakes, and 69 at Wilden. There are three other notable counts of twenty or more birds comprising: 28 on the 2nd May 1990 (as part of another massive passage across the Midlands), 26 on the 15th September 1974 and 20 on the 1st May 1965. More recently 19 birds were present at the Moors Pool on the 8th May 2008. Movements of Black Tern often coincide with the occurrence of Little Gull, as happened yesterday.

In line with the rest of the West Midlands there was a notable down-turn in records in the late 1970s and early 1980s, with blank years in 1978, 1979, 1981 and 1982; in more recent years there were nil returns in 1999 and 2007. Upton Warren just edges out Bittell Reservoir as the most visited site in Worcestershire although Bittell does tend to generally attract larger flocks.

A Billion Birds a year killed!!!!:-C


http://www.thepetitionsite.com/takeaction/206/194/838/?z00m=22865201&redirectID=1652067839Serious violations of animal conservation laws are happening all across Europe - and birds are dying as a result. Of the five billion birds that fly through Europe each autumn to spend winter in warmer weather, up to one billion are killed by humans.

We have to protect these birds before they become extinct. Sign the Care2 petition today urging the European Union (EU) to enforce laws to stop the illegal hunting, poaching, killing and smuggling of birds!

Within the borders of the EU, birds have had special conservation status for decades yet far too many are still hunted and killed. The Amur falcon, lesser whitethroat and songbird are at particularly high risk. In fact, hundreds of thousands of songbirds are illegally shot and exported every year.

Particularly in southeast Europe, hunters have become the number one threat for birds. They use guns, spring-loaded nets for water birds, poisoned prey and sticks covered with glue to catch the unsuspecting birds.

It's up to us to convince the European Union to stop illegal bird hunting before it's too late. The passenger pigeon was once the most common bird on the planet, but human actions led to the bird's extinction over a hundred years ago. Let's make sure we don't lose the Amur falcon, lesser whitethroat and songbird the same way - sign the Care2 petition today urging Europe to stop illegal bird hunting!

A bout of chickenpox for my eldest meant neither a day twitch to Bryher or an early start at Upton. When I rocked up to the reserve mid afternoon I was full of hope but it was soon clear that the biting ENE wind had put pay to much movement.

Black Tern Chlidonias niger

... or another juvenile present at the Flashes from the 14th October until the 29th October 2000 when it was forced off by floods The annual report for the West Midland Bird Club considers the October 2000 record to be the same as a bird seen in late September, resulting in a 32 day stay between the 28th September and 29th October 2000, believed to be the longest staying individual observed in the West Midlands region.
That's a bit of a leap of faith isn't it?

To quote from the Upton report for 2000 "A juvenile was then seen at the Flashes on the 26th (September), with possibly the same bird from 28th to 1st October. Another juvenile appeared at the Flashes on the 14th October..."

This would suggest that the bird remained 'hidden' or unreported for 13 days, which would seem unlikely given the number of visitors has on a daily basis.

I can only conclude that the suggestion of the same bird arose from a misinterpretation of the highlighted part of the above extract from the Upton report?

Wouldn't disagree Mike having reviewed the evidence - 13 days is a long time between sightings
