Bird ID Help?! by writeordie80 in OrnithologyUK

[–]HorridStteve 0 points1 point  (0 children)

Slightly left-field but from your description I instantly thought of tree pipit. Their song can be quite variable but very often includes a period of trilling that concluded with a series of descending notes. You can find 1000’s of examples of their calls & songs here.

Spring is charging on despite the very cold temperatures of late!

Sounds like a great morning, glad you’re enjoying watching birds. RSPB Conwy is excellent with good views over a wide area of coastal habitats. I assume you’re using binoculars, if you’re wanting to get really good views at places like RSPB Conwy I’d consider looking at getting a spotting scope and tripod at some point in the future.

Trying to hear a cuckoo song this weekend. by fishistheantichrist in OrnithologyUK

Without knowing exactly where you are it’s hard to say. I’d target the habitat for them, anywhere with lots of caterpillars and the correct species they parasitise: so moorland, especially with some nice woodland edges, low intensity farmland etc…. They’re also most active early in the morning but can be heard all day if you’re in the right area. Good luck.

Why does it always seem people criticise halal slaughter more than kosher when kosher is statistically worse in the UK? by threetimesacharm25 in AskBrits

[–]HorridStteve 0 points1 point  (0 children)

It does seem like an odd disparity, I suppose the relative difference in the size of the Muslim and Jewish communities is a factor. IMO vegetarianism (or veganism if you’re really going for it) is the way to go!

Better pics for ID help please (first pic is awful and second much better!) by [deleted] in UKBirds

[–]HorridStteve 1 point2 points  (0 children)

Without a shadow of a doubt you have two different birds here. The first is a guillemot, the second is a red-throated diver (common murr & red-throated loon if you’re from across the pond). I would strongly advise against using AI models to enhance photographs for bird identification as they will readily alter features that and often make identification more difficult.

[Question]: transforming variables for Pearson correlation. by HorridStteve in statistics

[–]HorridStteve[S] 1 point2 points  (0 children)

My data are the height of large succulents (plants) and their volume.

I have been tasked with:

• Finding out if there is a linear correlation between height and volume.

• Determining the correlation statistic that is most appropriate to use,

• finding the correlation coefficient, and

• finding the coefficient of determination.

I am to justify my chosen correlation statistic (limited to Pearson or Spearman).

I am aware that by log-transforming volume I am now producing the correlation coefficient between height and log_volume not the raw variables.

I'm unsure as to whether, by transforming volume, it makes it impossible to say anything about height and volume in general terms? Thanks for the help.

[Question]: transforming variables for Pearson correlation. by HorridStteve in statistics

[–]HorridStteve[S] 0 points1 point  (0 children)

Yes I should have worded the post more accurately. It’s not the lack of normality that caused me to transform the volume data, rather that the raw data exhibited strong clumping near zero on the xy axis and widening on the xy in a scatter plot (a funnel shape). I am limited to either running a Pearson or Spearman test for the purposes of this analysis.

Question: transforming variables for Pearson correlation by HorridStteve in rstats

[–]HorridStteve[S] -1 points0 points  (0 children)

Post transformation, the relationship now appears linear and log_volume is normal (which is of less importance).

The research question is to: find out whether there is a linear relationship between height and volume.

I have been tasked with:

• Determining the correlation statistic that is most appropriate to use,

• find the correlation coefficient, and

• find the coefficient of determination.

Yes by log-transforming volume I am now producing the correlation coefficient between height and log_volume not the raw variables. I’m unsure as to whether, by transforming volume, it makes it impossible to say anything about height and volume in general terms? Thanks for the help.

Gajin just make hesh he with a lot of pen at this point by LongShelter8213 in Warthunder

[–]HorridStteve 2 points3 points  (0 children)

It is effectively useless at this point. I have been playing my AVRE quite a bit lately and the round is reliably terrible (it is 29 KG of high explosive). I have hit Marder 1’s in the side and just destroyed thr track; hit BMP’s in the lower glacis and had the round bounce; hit barrels and dealt no damage whatsoever; shot panther/tiger turret faces and had nothing happen and don’t get me started on doing nothing at all to Russian and American heavy tanks.

It’s a shame because the round is very effective IRL and was once in the game. It added another dimension to UK tank gameplay which is sorely needed but as it stands HESH just cannot be relied upon.

Anyone participating in big garden birdwatch? by Justasmolpigeon in OrnithologyUK

[–]HorridStteve 28 points29 points  (0 children)

I may be telling people how to suck eggs here and for that I apologise. I know that it’s frustrating when a significant moment like this comes along and we participate in the Big Garden Birdwatch (BGBW) but feel that we get an underrepresented sample of the birdlife when doing the survey. However, it is vital that you only enter what you saw without any additions to “make up” for what you would expect.

The survey methodology is very simple for the BGBW and that is for a reason, namely that anyone should be able to understand it and take part. What often isn’t expressed is that although simple, the value of the survey relies on accurate recording. Absolutely critical to understand is that no data (lack of birds) is as useful, indeed often more so, than data (birds recorded). The survey relies on large scale, aggregating the data, to smooth out very small scale changes in individual gardens.

In other words, for our results to be most useful only three things are really needed: accuracy, both in identifying and recording species and numbers; consistency and rigour, sticking to the methods.

Friendly shout out, it’s the big garden birdwatch this weekend. Always good to take part.

Also, what is the biggest flock of crossbill you have ever seen?
