A Happy New Year to all!

This will probably end up as a vague ramble but I'm wondering whether anybody else has "added" sightings and found that they somehow got lost in the ether.  I have just finished adding an entire wadge of sightings from a trip and have run a complete list, only to find that many of my observations have apparently disappeared.  Has anybody else noticed anything similar?

To give a bit more detail, I add sightings by location and time/date by clicking on entries in the appropriate checklist and adding comments when I have anything to note.  I click on "Add sightings" and compare the total number of sightings the program reports with the number of entries in my field notes.  If the two totals agree, I click on "Yes"; otherwise I go back and check to see what I've missed.  I then go on to the next location I visited and so on.  Peculiarly, though, it seems that even though the program tells me that I'm adding, say, 100 species, only 99 entries are actually added to the "Sightings" database (this isn't a problem with my choice of taxonomic list - when I go in to the Access database I can see that only 99 entries have been added).

Obviously I can add sightings and then use "view/edit" to check that the program really has added 100 sightings but this is a drag.  As I've been using the program for years without any problems (although my numerous previous posting provide some evidence to the contrary) I don't think I'm doing anything wrong.  But as I've learned, idiots have the wonderful ability to cause difficulties to even the most idiot-proof programs so I can't be sure.

I guess I should say what version of the program I'm running but I confess I can't remember.  I'll check at home if it's important.

Does anybody have any thoughts?

Best wishes,

Graham

Hello Graham,

This is rarely reported, and when it is, it always ends up being something logical, such as a filter setting when retrieving the sightings, or not asking for subspecies when the missing sighting was for a subspecies, or using one tax list to enter the sightings and another to retrieve the sightings (the 2nd tax list not having the 100th thing in question), etc.

Also, give me the details please on exactly how you enter sightings: checklist or keyboard mode; tax list, location filter, any other settings at all (a screenshot of your sightings entry setup window would do also). If Checklist Entry mode, which style do you have checked? Do you ever use the "Add Name" button? If you use this, it can add any name in your database - even though it is not attached to the currently used tax list - and therefore will not show when you try to retrieve your sightings by that tax list. For example, Let's say you are using the ABA tax list, and you saw a Fox Squirrel on your trip; you could use the Add Name button to add the Fox Squirrel to your current checklist entry grid - but that sighting won't show up when you go to retrieve sightings using the ABA tax list.

You should be running v3.6.49, but please do check when you get home - just to be sure.

With the thousands of BD users, I can't imagine a bug like this going for 1 month (let alone the 4 years that 3.6 has been out) without dozens of users reporting it. But, still, you never know. This is what I would do... if you have notes that says (using your example) you have 100 sightings, and you think you entered 100 sightings, and now you can only pull up 99 of the 100 sightings you believe you entered... go through your notes and find the missing sighting that is in your notes but not in BD. Try searching for that sighting using a broad filtering; e.g. only specifying the date of those entries; or all entries for that thing or location; etc. And see if that sighting doesn't show up, but under settings that you were excluding based on earlier filters in use.

Things like the above always tend to be the answer. If BD were simpler and only allowed you to use one tax list without so many filters etc, these types of things would tend not to trip people up; but it happens every now and then.

Let me know what you find and how I can help. The absolute key is to find the sighting in your notes that you feel you entered but is missing in BD. You have to start there. Let me know.

Jeff

Dear Jeff,

Thanks for the lengthy answer - much appreciated. I'm now at home and have taken a fairly long look at the sightings I recently entered. It turned out that there at least ten have gone awol - I haven't finished checking so the real number could be higher - and I am reluctant to believe I made so many mistakes when I was going through my notes (but see below).

The solution may be completely trivial as it turns out that I'm running v 3.6.29 (with database 3.6.29). Have I really missed so many upgrades to the software? I guess I should download and install the current version and see whether it makes a difference ...

If this isn't the reason, though, I'll have to look harder. To answer your questions, I'm sure it isn't a matter of different taxonomic lists as I have gone into the Access database (yes, the one that gives me a table of numbers) and checked how many things have been entered at the particular time and date in question: n-1. I use the checklist entry method with the Clements list (2008 version; I think I was off birdwatching when the 2009 version came out and never got around to making the upgrade but this shouldn't be a problem) and filtering for Argentina. I do use the "Add Name" button occasionally but am careful that the "thing" I add is in the Clements list.

I could list some missing sightings (Brushland Tinamou, Crested Duck, Cocoi Heron, Andean Lapwing, Striped Cuckoo ...) but please believe me that these are perfectly normal species for which I have many other sightings in my database (which may be why I didn't pick up the problem earlier: I tend to remember my important sightings and forget the padders!)

Perhaps I should also mention that I frequently noticed that when I was adding sightings an item that was checked in the checklist entry failed to show up when I clicked on "Review Sightings". In such cases I simply removed the check and then reentered it and the problem disappeared. But the sightings entry was more problematic than I had ever experienced before and I wondered whether this might be something to do with the size of my database. Is there a point above which strange things start happening? I could check - BD is on a different PC from the one on which I'm working at the mo - but would guess that I have entered something like 90-100,000 sightings.

Finally, I must admit that the failure of anyone else to come out in support seems to suggest that we're dealing with a "pilot error" of some kind. As you say, BD 3.6 has been around for such a long time and is used by so many people that a bug of this type would have been bound to be picked up by someone. Although I am always extremely careful when I transcribe my notes into my database - weeding out mistakes takes such a lot of time - it may simply be the case that my handwriting and/or my eyesight have deteriorated to the extent that I can now longer perform this simple procedure correctly.

All the best,

Graham

P.S. What's a Fox Squirrel?

HI Graham,

"Eastern/Red Fox Squirrel" - Sciurus niger. Tree squirrel in eastern (moving west) NA.

I can empathize with the eye-sight and hand-writing problems. I am getting my first pair of prescription glasses ever, tomorrow. Tired of having one pair around my neck for reading, one for the computer and one for all other vision. Been on computers since 1978, so I have basically never handwritten anything since, and if I try - well forget it, it isn't readable.

I doubt it is 3.6.29 - but you never know. Please run the 3.6.49 installation (it is free) from the Downloads page on this web site by clicking on the Network Installation link - on all your systems. It is very quick and will get you upgraded quickly to eliminate that as a possible problem.

I am concerned about your report that the Review window sometimes does not show you all the checked off things. This may be fixed when going from .29 to .49.

No - your database size should not have anything to do with this.

Perhaps you can create a test observer and see if you can reproduce this problem usign the test observer. Just try a couple different rapid checklist entry sessions with the test observer and see if, 1) you can reproduce it, and 2) if you can figure out what causes it to happen.

Let me know please,

Jeff

Dear Jeff,

Thanks for the sympathy on my eyesight. I don't have glasses of any kind but fear that the time may be rapidly approaching when there'll be no way around them, at least unless I learn to write larger.

I am reluctant to think that I could have made so many mistakes entering my sighings when I came back from Argentina. The mistakes I do make are by clicking on the wrong box (thereby entering the wrong species) but I usually pick these up when I scan over the data. But I never click on "Yes" when asked whether I'm sure until I've checked that the number of species I'm adding is correct. In my recent data bash this was often not the case but it now seems as though the program sometimes told me it was adding n sighings although it was really only adding n-1 (and I've found one case of n-2).

All most puzzling but I'll follow your advice and install 3.6.49 (so expect some mails from me asking for authorization codes: I'm the one with multiple PCs and BD on a machine that is hermetically isolated from the Internet). I'll then try creating a test user and reentering at least some of my sightings from the Argentina trip. If I encounter problems I'll let you know but rest assured that you'll now have me off your back for a while as I don't have time - or the mental energy - at the moment to start bashing in thousands of sightings again.

Oh and thanks for the information on the squirrel. For some reason I thought all your squirrels were grey ...

All the best,

Graham

Dear Jeff,

Well, I'm now running 3.6.49, although I haven't really used it much as I've been away a fair bit recently. This afternoon, though, I tried to work through some of my backlog of entering sightings and noticed the following:

i) the times were never included in the date field - I had to edit manually all my sightings to add the time, which is easy enough but takes time (groan).

ii) there was at least one case where I added 61 sightings (for a particular location at a particular time) but only 60 sightings were added to my database. The missing one was Common Ringed Plover, a perfectly normal species in the taxonomic list I was using (Clements 6.3.2) so I'm at a loss to explain what went wrong. I'll keep monitoring carefully - in view of the missing time problem I now enter sightings and then immediately review them to add the time, so I notice immediately if something is wrong - and keep you in touch.

Perhaps these are known bugs that have been fixed in release 6.7? The time problem seems new, though: I had never had the problem with any previous release.

All the best,

Graham

Hello Graham,

i) the time is not registered for a sighting unless you manually specify it. You must manually specify the time on each entry.

ii) there are no known problems with sightings not being entered or going away. Usually when these things come up, the sighting was inadvertently entered under a different location or time (or incorrect name) and searching for it doesn't find it due to this.

Dear Jeff,

i) I know that! I've been entering sightings with times for years and never had problems until I upgraded to 3.6.49. I have been clicking the box and specifying the time for (nearly) all of my sightings, honest!

ii) I haven't managed to work out when sightings "disappear" because it happens too infrequently for me to be able to derive a pattern. I'll run the 3.7 upgrade and continue entering my sightings (I have a horrible backlog to take care of) and shall record any cases of things that look strange. I'm using the "checklist entry" method and then view/edit sightings after each time I click "add sightings" so that I can manually add the time - see (i) above. This means that it's easy for me to notice things that go missing ...

Best wishes,

Graham

Hi Graham,

One thing that does trip folks up is that if the width of the date/time field in the View Sightings grid changes (gets just a bit shorter) then the time will not show unless you widen that field. It will truncate the time and just show the date due to column width. The time hasn't gone away, just truncated. One way to tell if this is the case, is to edit such a sighting and see if the time shows in the time field; or drag to widen the date/time field.

Just a thought,

Jeff

Dear Jeff,

Good try but no, this isn't the explanation! I display the grid with enough width to see time and date and indeed the time is shown for all previous sightings (i.e. the ones I entered with 3.6.29 and the ones I've edited with the View/Edit Sightings option in 3.6.49).

I really do think I might have stumbled upon a bug here. But I guess it doesn't matter now that 3.7 is waiting to be installed (but not today; too much "real" work to do).

All the best,

Graham

Wow! Good find if we can reproduce it. It would be truly odd if the time got written to the database (you say that it used to be there for these records - right?) and then somehow disappeared. I can'timagine what would cause saved records in the database to remove the time portion of the date/time field. Please let me know if/when you stumble across any ideas. I have just been testing myself some additions, edits, etc and can't seem to get the time to disappear when it should not.

Dear Jeff,

Sorry, no, I can see I've been unclear as usual. What I mean is that the time is not written to the database although it should be. The saved records in the database are left untouched - thankfully.

Next time I can play around (maybe this evening, although I can't promise it) I'll take a shot of the screen just before I click on "add" and another one when I view/edit sightings so you can see what I mean. I admit that the most likely explanation is pilot error but I can't for the life of me understand what I'm doing wrong and as I've been using the program for a very long time and am far too boring to change the way I work I tend to look for other reasons. The obvious thing that changed when the dates stopped being entered was that I upgraded from 3.6.29 to 3.6.49.

All the best,

Graham

Dear Jeff,

I'll try to be a touch clearer on what I mean and perhaps you can let me know what I'm doing wrong.  I use the checklist method to enter sightings, as in picture 1, which shows me about to click on "Add Sightings" having entered time and date, as well as location etc.

With previous releases (up to 3.6.29), everything was entered correctly into the database (apart from the odd missing record - see the main thrust of this thread) but the result with 3.6.49 is shown in the second picture - the sightings are entered correctly but without the time.  I can naturally use "View/Edit Sightings" to add the time manually - picture 2 shows me about to do so - but this is a bore and entails more work every time I add any sightings to the database.

Am I doing something incredibly stupid or is something strange happening?  More to the point, can anybody reproduce the problem or is it a peculiarity of my system?  And even more to the point, will the problem persist with 3.7?

Best wishes,

Graham

Hello Graham,

Well - I'll be darned. v3.6.49 does NOT save the time. I confirmed the same behavior on my system. But v3.7 does save the time. And, as you have found out v3.6.29 saves the time also. I don't know what happened in there; but v3.7 does it correctly. You are not doing anything wrong.

So, my question, why aren't you using v3.7?

Jeff

Dear Jeff,

You don't know how happy it makes me to hear that I'm not an idiot - at least not this time ...

I'm not using 3.7 because I know that 3.6.49 works (I have just led a couple of trips and need to enter my sightings before I can produce the reports people are waiting for) and because I don't have the codes to unlock 3.7 yet!

All the best,

Graham
